Abstract

In this study, a novel adsorptive membrane was prepared from chitosan as the functional polymer and some additive blend solutions by solution casting method. The modified chitosan membrane was characterized by FTIR and its Water Swelling Ratio (WSR). The adsorption of copper ions on the adsorptive membrane was investigated in batch experiments. The results obtained from the experiments indicated that the membrane had a good adsorption capacity for copper ions, the optimal ionic strength and pH were 0.1 and 5-6, respectively. Compared with the Langmuir isotherm model, the experimental data were found to be following the Freundlich model.

Key words： chitosan; adsorptive membrane; copper removal; environmental engineering; heavy metal; isotherm model
