Can you do leafy or clover headcanons please :)

I can do both

Leafy Sexuality Headcanon: I could see her as bi but with a preference for men Gender Headcanon: Girl with a question mark sound. I don't wanna label her a cis girl but like I don't really have a solid gender concept for her :0 certainly fem leaning but like maybe a demi-girl? A ship I have with said character: I am not too fussed abt shipping w/ leafy. I guess I can say I don't mind Fiery x Leafy cause it's p popular, but I'm really not super into any Leafy ships. Leafy x Pin is cute, I think I saw that before? A BROTP I have with said character: Man, honestly Leafy is a chara I struggle on just cause- she wasn't in bfb much due to getting out early and then when I watched the original bfdi I jsut was struggling through it so I paid no attention to character interactions. But! I do like art with fiery and leafy interacting and hanging out. Like sure its ship art most of the time, but idk, I just like them hanging out. A NOTP I have with said character: Not fussed abt notps for leafy :0 Can't think of anyone I'd actively not want to see with her. A random headcanon: I like making her like, a little leaf bug crossed w/ a kangaroo for my creature design xD And she can just spring away so far, jsut, nyoom. General Opinion over said character: I wiiiiish I could see what everyone sees in her, I wish I found bfdi as a kid before I had highe opinions on animation and writing; But since bfb was my first watch of the bfdi universe, and leafy got out early, I jsut was so confused abt her character? Like ok, she puts up a facade of being nice and she really tries to people please, but then when she comes back later she- just seems different? Like she just turned it down a number of notches. But like, why, what changed in the EXIT that made her more chill. I really do want to like her!! But I just don't really have a solid view on what her character is and it kinda confuses me. Clover Sexuality Headcanon: She likes girls, I struggle to see her with a guy or a generally masc person for some reason Gender Headcanon: Feminine for sure, but I don't think she would care too much abt gender. Maybe she would experiment with some pronouns like bun/bunself or a butterfly type neopronoun. A ship I have with said character: I actually think Clover x TBD is kinda cute just cause cute charas, but I'm not too big on Clover ships? I think she would be neat with a lot of the s2 gals tho :0 A BROTP I have with said character: Her and Nickel's dynamic is fun, I wish we could see Nickel warm up to her cause I like them w/ a sort of sibling style dynamic with Clover being a kind of older sister figure. Would like to see her interact with people like Soap or Salt or Pepper, just curious how that would go. Heck, I think she could take over the world if she met Taco and was convinced, buuuut then she'd see a butterfly and be like Oh ok time to do some wandering :) and jsut leave. A NOTP I have with said character: I hesitantly say shipping her with Nickel; thanks to a youtube map I watched I prefer them as sibling dynamic. So not so much a notp as much as just I would kinda squirm if I saw it but could probably be convinced I guess? A random headcanon: She randomly wanders away from contestant grounds during off time and will just turn up in a town like 50 miles away after 1 hour and no one knows how she got there. She always manages to get back tho. General Opinion over said character: Oooh she's so cute and she's very funny. Her exit interview was probably my fav peak into her character cause she was kinda backhanded? She's like "If I really had my luck I wouldn't be talking to you :) " Like she basically said Pls frick off to her interviewer but in a nice way. I jsut think we didn't see enough of that character side of her in the show. Really wish we could get more Clover content! I'm hoping that ii does something post season 3 like the comics but w/ s3 characters in hotel oj too, just cause I want that interaction content so bad.

Evaluation of Green Clover Leaves as Green and Economic Sorbent for Removal of High Levels of Iron from Different Water Sources

Authored by Hassouna MEM

Abstract

Green clover powdered leaves and their modified forms with lactic acid and tri sodium citrate have been used as low cost and eco-friendly adsorbents for the removal of iron from aqueous media. Samples were collected from different water supplies (surface, tap and ground water).The different factors affecting the adsorption procedure such as: adsorbent dose, stirring time and pH have been optimized for the sake of realizing maximum removal efficiency. The removal efficiency of the unmodified green clover was increased with the increase of the pH value until reaching its maximum uptake in the range 4-7. Both the sodium citrate and lactic acid modified green clover powders showed maximum uptake in the pH range 5-6. The removal process was slow in the first 35 min. then the uptake% was gradually increased till equilibrium after 50 min in case of unmodified green clover, the tri sodium citrate modified form showed equilibrium after 40 min. and the lactic acid modified one reached equilibrium after 50 min. Desorption processes proved the possibility of regeneration and reuse of the adsorbent.Modified forms displayed better adsorption capacity and capability comparable with that of the crude leaves. The removal process was applied on some samples of wastewater successfully.

Keywords: Water sources; Heavy metals; Fe; Green clover leaves; Economic sorbent; Adsorption

Introduction

Air, food, soil and water were narrated to be the media where heavy metals such as copper, cadmium, nickel, lead, and zinc are introduced into the environment [1-4]. Heavy metals cause serious health disease, including reduced growth and development, cancer, organ and nervous system damage. In severe cases, it leads to death [5]. These heavy metals are reported to be hazardous resulting in damage to ecosystems as well as human health [6,7] especially if their concentration is more than the accepted limit [8]. Their higher sources include contaminant water discharged from hospitals [9], several industries such as Cd–Ni battery, metal plating and alloy manufacturing [10-13]. Chemical precipitation, ion exchange, electrodialysis, solvent extraction, coagulation, evaporation and adsorption are among the most known techniques for the removal of metal ions from aqueous solutions [14-17].Iron is one of the earth’s most spreading resources making up about 5% of the earth crust. It is one of the major heavy metal impurities that are commonly present in many water sources which cause several problems for the human health [18]. There are many methods for removal of iron from ground water, viz., oxidation with chlorine and potassium permanganate, treatment with limestone, liquid–liquid extraction, ion exchange, chemical precipitation, bioremediation, activated carbon and other filtering materials [19-23]. Many of these methods became not economically feasible for the removal processes.In recent years, the need for safe and economical methods has necessitated the use of low cost agricultural by-products such as sugarcane bagasse [24-26], rice husk [27,28], sawdust [29,30], coconut husk [31], oil palm shell [32], black gram husk [33], neem bark [34] , tea waste, turkish coffee and walnut shell. Some more adsorbents like papaya wood [35], maize leaf [36], teak leaf powder [37], coraindrumsativum [38], lalang (Imperata cylindrica) leaf powder [39], peanut hull pellets [40], sago waste [41], saltbush (Atriplex canescens) leaves [42,43], tree fern [44-45], grape stalk wastes [46], etc. Sorption methods are considered flexible and easy to operate with much less sludge disposal problems and economically feasible [47,48].However, the expense of individual sorbents varies depending on the degree of processing required and local availability. In general, an adsorbent can be termed a low cost one if it requires little processing, abundant in nature, an agricultural waste or is a by-product or a waste material from an industry. On the other hand, plant wastes can be used in their crude form, or in most cases, require to be modified or treated for being applied for the cleansing of heavy metals. Thus, the present study was forwarded towards the use of green clover powdered leaves as economic sorbent in both crude and modified forms with tri sodium citrate and lactic acid for removal of iron from different water sources. The different factors affecting the adsorption procedure such as: adsorbent dose, stirring time and pH have been optimized to achieve maximum removal efficiency.

Experimental Materials and Methodsa) Chemicals

Ferrous ammonium sulphate (Aldrich), Hydrochloric acid (BDH), 1, 10 Phenanthroline(Aldriin 0.1M HCL,) Tri sodium Citrate(Aldrich) and Hydroxylamine hydrochloride(Aldrich).b) ReagentsGreen clover leaves are collected from the agricultural Egyptian fields. The leaves are washed, air dried and then are finely powdered in a mixer till being near the nano size. The final product is applied as the crude green clover leaves powder for the removal of iron from water samples according to the proposed procedure.100 g of the crude green clover powder are refluxed with 500 ml of 0.5M lactic acid solution over a boiling water for 6h.The produced precipitate was separated, repeatedly washed with DDW till free from acid then dried in an oven at 60ºC for two hrs. After cooling in a desiccator to room temperature, it is finely grinded once again.100 g of the crude green clover powder are, similarly, refluxed with 500 mL of 0.5 M trisodium citrate solution over a boiling water bath for 6 h. The produced precipitate was separated, repeatedly washed with DDW till free from both the sodium and citrate ions, then dried and grinded.UV/Vis. Spectrophotometer (Shimadzu UV/Vis. Perkin Elemer Lambada 3B Spectrophotometer using 1cm Quartz cell” was used in the determination of residual iron in the effluents after the adsorption processes); Flame Atomic Absorption Spectrophotometer AA 240FS, Agilent Technologies, used for rapid and confirmational determination of iron; pH meter (The pH measurements were carried out using the microprocessor pH meter BT 500 BOECO, Germany, which was calibrated against two standard buffer solutions at pH4 and 9 and Mechanical Shaker (with up to 200 rpm with speed control was used).The morphologies of the prepared samples and composites were investigated using Scanning Electron Microscopy (SEM), X-Ray diffractometer was used to investigate the phase structure of the investigated samples under the following conditions which were kept constant in all the analysis processes Cu: X-ray tube, scan speed = 8/min, current = 30 mA, voltage = 40 kV and preset time = 10s.The residual iron in the solution is determined spectrophotometrically after its reduction to Fe (II). In a 25 ml volumetric flask, add 0.5 ml of the 10% hydroxylamine solution, 2 mL 10% tri sodium citrate solution then transfer 5 ml of the standard Fe (II) solution. The pH is in the range 3-4. Add 2.5 ml of 0.2 % 1, 10 phenanthroline solution, dilute to the mark with DDW and mix thoroughly. After 5 min the absorbance of the solution is measured at 512 nm against a blank.The concentration of residual iron in the solution after the adsorption process is directly measured at λmax equals 372.0 nm with detection limit of 50μg/L using a mixture of Acetelyne –Nitrous Oxide flame.To investigate the effect of pH on the uptake % (adsorption) of iron from aqueous media by the crude green clover leaves powder, aliquots of 25 mL containing 20 ppm of the metal ion are transferred to a group of 100 mL conical flasks each containing 0.1 g of the crude adsorbent. Adjust the pH of each flask to a value ranging from 2-10, respectively using 0.1M NaOH and HCl solutions and stir for 1hr. Centrifuge the contents of each flask and determine the residual iron content in the supernatant solution. The sorption percentage of the metal ion by the green clover leaves powder is calculated from the relation:Uptak e (%) = [(Co-C) / Co] ×100Where Co and C are the initial and final concentrations of metal ion respectively. The optimum pH was found to be in the range 4-7.When the same procedure was parallely repeated using the sodium citrate and lactic acid modified powder instead, the optimum pH was in the range 5-6.Aliquots of 25 mL solution containing 20 ppm iron are transferred to a group of 100 mL conical flasks. Adjust the pH of each flask to the optimum value. Varying amounts of the crude green clover leaves powder in the range 0.05 - 0.35 g are added to each flask, respectively. The mixtures were stirred for 1h. The residual iron content in the supernatant soln. separated by centrifugation is determined spectrophotometrically.A group of 100 mL conical flasks, each of which is charged with 0.2g of the crude green clover leaves powder and aliquots of 25 mL solution containing 20 ppm of iron at the optimum pH and the shaking time is changed for different intervals of time (10-80 min.) for each flask in its role, respectively.Applying the optimum conditions of the weight of green clover leaves powder, pH and stirring time in a group of flasks. Aliquots of 25 ml solution containing varying concentrations of iron in the range 10-100 ppm are added to the flasks, respectively. The same procedure is applied and the residual iron content is determined from which the uptake percent is calculated.Different volumes of iron samples in the range from 10-100 mL were used.Results and DiscussionCellulosic materials and their derivatives have shown quite good metal ion adsorptive capacity. Among all the heavy metal removal techniques reported so far, adsorption technique using cellulose-based agricultural waste products appears to be most attractive since it is an effective and relatively simple method for removal of heavy metal ions. However, the leaves and pseudostem are usually discarded as waste products of the food and herbalism industries.The use of plant’s leaves is reported in literature for the removal of various heavy metals from wastewater e.g., adsorption of thallium(I) ions using eucalyptus leaves powder [10], the adsorption of lead by maize leaf [36], Cu(II) by teak leaves powder [37], Pb by Lalang (Imperata cylindrica) leaf powder [39], Zn(II) by leaves of saltbush(Atriplex canescens) [42,43] , by cypress and cinchona leaves [49], Cr(VI) by black tea leaves [50] and biosorption of Cu(II), Pb(II), and and Cu(II) ions in aqueous solutions using Mangifera indica (Mango) leaf powder [51].Hence, the thinking of trying green clover leaves fine powder as a low cost adsorbent for the treatment of a real local problem viz., the flourishing existence of iron (and manganese) in the ground water of some wells at El-Wasta, a town which lies 35 Km to the north of Beni-Suef Governorate.Different factors that affect the adsorption process have been extensively studied to improve the uptake % of iron from the aqueous solutions.The pH of the aqueous solution plays the most important role in the adsorption process. It not only influences the speciation of metal ions but also the charges on the sorption sites. The results indicated low sorption efficiency at low pH values (pH=2-3). This was attributed to the high concentration and high mobility of H+, which are preferentially adsorbed rather than metal ions [52,53]. The removal efficiency of the sorbent is increased by increasing the pH value until reaches its maximum uptake at the range 4-7 by the unmodified green clover. The sodium citrate and lactic acid modified green clover powders showed maximum uptake at pH range 5-6 (Figure 1). Heavy metal biosorption onto specific and non specific biosorbents is pH dependent; other researchers [54] found that an increase in adsorption is a result of increasing the pH of the solution (Figure 1).The amount of removed metal ions by adsorption depends on the time after which equilibrium is reached, this is expressed as the equilibrium time. The results indicate that removal was slow in the first 35 min then the uptake % was gradually increased till equilibrium at 50 min for the unmodified powder. While the powder modified with tri sodium citrate shows equilibrium after 40 min and the lactic acid form reached equilibrium after 50 min. The rate of biosorption seems to occur in two steps, the first one is very rapid surface biosorption, while the second is slow intracellular diffusion (Figure 2).The biosorbent dose is considered the most important parameter affecting the removal efficiency. For the unmodified powder, a dose of 0.35 g sorbent has achieved an uptake of 91% of iron at optimum pH conditions. While for the tri sodium citrate modified form, a dose of 0.25 g achieved an uptake % of iron of 97.5%. Correspondingly, 0.25 g of the lactic acid modified one achieved iron removal of 93.5% (Figure 3)At lower concentrations the adsorption sites utilized the available metal ion more rapidly when compared to higher concentrations where the metal ions need to diffuse to the sorbent surface by intra particle diffusion. The maximum metal uptake was 92 % in the case of the unmodified green clover, 94% for lactic acid modified powder and 97% in the case of tri sodium citrate modified form at metal ion concentration of 10 ppm (Figure 4).At optimum conditions the volume of 25 mL achieved the best adsorption percentage with all tested green clover leaves powders. It is clear from the figure that iron removal decreases with the increase of volume (Figure 5)Structures and morphologies of the crude green clover powder, its loaded composites with lactic acid and trisodium citrate ones are studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM) (Figure 6). Anchor scan parameters, graphics and the peak list for every xrd scan. These scans assure the successful loading (modifying) of the crude green clover leaves powder with the two modifiers viz., lactic acid and trisodium citrate. Modification succeeded in increasing the removal percentage, but hasn’t had any improvement effect on selectivity.XRD scans assures the successful loading of the crude powder with the two modifiers used.Adsorption studies applying the three adsorbents, under study, proved that they are nonselective towards heavy metals that may be present in wastewaters as pollutants. The spiking of the iron authentic samples with different concentrations of other metal ions e.g., Fe(III), Mn(II), Ni(II) and Cu (II) resulted in additive concentrations of the collection of metal ions present in a solution without any discrimination among them.However, the non selectivity of such types of adsorbents is frequent in the literature, their tolerance is attributed to being low cost and available. Current work in our laboratory is devoted for the development and applications of selective and low cost adsorbent.The adsorbed iron ions on the adsorbent surface are treated with 25 mL 0.1M HCl and stirred for 1h. The amount of iron ions remained in the solution after filtration or centrifugation was measured using the recommended spectrophotometric method and the percentage desorption (Rb) was calculated according to the relation:where Ct is the experimental concentration in the solution at time t (ppm), Ca is the adsorbed concentration of sorbate onto the adsorbent.i. Effect of pH on desorption of iron: In strong acidic media at pH range(1.4-2.2)the three forms of the green clover leaves powder showed high desorption percentages, on increasing the pH values desorption percentage decreases (Figure 7).ii. Stirring Time: The desorption percentages % were gradually increased till equilibrium at 35 min for the unmodified and lactic acid modified powders, while the powder modified with tri sodium citrate shows equilibrium after 40 min. A value of 89% has been recorded for the unmodified green clover powder, 93% for the trisodium citrate modified form and 91% for lactic acid one (Figure 8).iii. Real samples: Water samples collected from tap water, Bahr Youssef water, ground water and Ibrahemia water, samples were subjected to the adsorption procedure as illustrated previously and the residual iron is analyzed by two methods of finish viz., colorimetry and AAS (Table 2).ConclusionGreen clover leaves powders proved to be potential biosorbents for the removal of iron from aqueous solutions being available low cost material. Results of desorption study also confirmed that there is a possibility to regenerate and reuse the biosorbent again.
