dc.description.abstract Rice husk (RH) cellulose as a matrix was synthesized for amine rice husk magnetic biocomposite (RB- NH2) by one-pot solvothermal method. The synergic effect of amine on magnetic nanoparticle will enhance the reactivity of material. Ethylene glycol as solvent was used for dissolved iron(III) chloride hexahydrate, Na-acetate anhydrate, and 1,6-hexanediamine, then RH was added, kept at ±200 oC for 6 h. The optimums of Fe contained and amine concentrations on biocomposite were detected at 93% and 2.9 mmol/g, respectively. The surface area of rice husk significantly increased from 1.309 m2 g-1 to 19.45 m2 g-2 when converted to biocomposite. The RB-NH2 has good capability to adsorb Cu(II) ion at 116.45 mg g-1 at pH 5 for 60 min. Surprisingly, during adsorption, the RB-NH2 also worked on reducing the chemical oxygen demand (COD) number, total suspended solid (TSS) and dye for 22%, 54.37%, and 33.74%, respectively. The reuse effectiveness for RB-NH2 showed a good result with four repetitions. The multiple effects of amine rice husk magnetic biocomposite on wastewater contaminants leads to becoming a candidate material to be developed and applied in a wide range of waste water treatment applications en_US
