摘要:Ferrocene (Fc) modified cation exchange resin (FMCER) was synthesized for copper adsorption process and characterized by XRF and BET analysis.Fc has been successfully impregnated into resin, and Fc loaded on resin was about 0.1792% (w/w).Both surface area and pore width of resin was enlarged.Results from batch experiments indicated that the adsorption kinetics of Cu2 obeyed pseudo-second-order kinetic model and the adsorption rate constant was 0.0011 g/mg/min.Langmuir adsorption isotherm model fitted the adsorption of Cu2 well.The adsorption process of Cu2 was exothermic reaction.The adsorption process was pH dependent and the optimal pH was found to be 4-5, and maximum removal efficiency was 38.59% at pH 4.
