Abstract:3+from wastewater,the Fe3O4magnetic fluid was prepared byco-precipitation method. The reduced graphene oxide (RGO) was prepared with hydrazine hydrate asreducing agent. Fe3O4@mSiO2-RGO magnetic mesoporous nanocomposite was synthesized by improvedStöber method. The structure of Fe3O4@ mSiO2-RGO was characterized by FT-IR,XRD,BET andmagnetic response method. The effects of adsorption time,initial concentration and adsorbent dosage onFe3+adsorption were investigated. The results show that when the oscillating reaction time is 40 min,theadsorbent dosage is 24 mg,and the solution concentration is 0.04 mg·L-1,the adsorption rate reach thehighest value of 61.8%. Fe3O4@mSiO2-RGO has ideal adsorption-desorption performance of Fe3+. Theadsorption process conforms to the quasi-second-order kinetic model,and includes both physical ad⁃361sorption and chemical adsorption. Close-
