Rice husk (RH) cellulose as a matrix was synthesized for amine rice husk magnetic biocomposite (RBNH2)by one-pot solvothermal method. The synergic effect of amine on magnetic nanoparticle will enhance the reactivityof 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 amineconcentrations on biocomposite were detected at 93% and 2.9mmol/g, respectively. The surface area of rice husk significantlyincreased from 1.309m2 g1 to 19.45m2 g1 when converted to biocomposite. The RB-NH2 has good capabilityto adsorb Cu(II) ion at 116.45mg g1 at pH 5 for 60min. Surprisingly, during adsorption, the RB-NH2 also workedon reducing the chemical oxygen demand (COD) number, total suspended solid (TSS) and dye for 22%, 54.37%, and33.74%, respectively. The reuse effectiveness for RB-NH2 showed a good result with four repetitions. The multipleeffects of amine rice husk magnetic biocomposite on wastewater contaminants leads to becoming a candidate materialto be developed and applied in a wide range of waste water treatment applications.
