Abstract

Magnetic Fe₃O₄/activated carbon composite have been prepared by hydrothermal reaction with homogeneous morphology. The value of saturation magnetization M_S > 10 emu/g was obtained. Langmuir isotherm model was used to investigate the adsoprtion of Alizarin yellow-G dye on Fe₃O₄/activated carbon composite. Results showed that the maximum adsorption capacities q_max were higher than 350 mg/g.
