Preparation of Activated Carbon/CoFe2O4 Composite and Its Adsorption Properties for Methylene Blue
Abstract:
Activated carbon/CoFe2O4 composite(AC/CoFe2O4,MAC) with magnetic seperation performance was synthesized via a low-temperature refluxing route.Batch experiments were carried out to investigate the adsorption kinetics and equilibrium of methylene blue(MB) onto MAC.The effect of initial pH value on MB adsorbed onto MAC was evaluated.It was found that the adsorption of MB onto MAC was a very rapid process,reaching to the equilibrium within 20 min.The pseudo-second-order rate equation could describe the adsorption kinetics of the MB onto MAC.The equilibrium data could be fitted well with the Langmuir equation.The saturated adsorption capacity obtained from the Langmuir equation was 120.48 mg/g.At lower pH values,adsorption capacity of MAC for MB was small,whereas it increased with increasing pH value.
