摘要：
We prepared alginate-chitosan (ALG-CTS) complexes through ionic interaction, and then obtained Cu (II)-imprinted alginate-chitosan complex microspheres (Cu-ALG-CTS) by coupling with ionic imprinting technology. To investigate the effects of experimental conditions on adsorption behavior, we performed a series of experiments including changing the initial concentration of Cu (II) ions and adsorption time. We found that the adsorption capacity increases with the initial concentration of Cu (II) ions. The Cu (II) ions adsorption reaches the maximum of 70.54mg/g after adsorbing for 13h when the initial concentration of Cu (II) ions is 60 mu g/ml. Cu-ALG-CTS shows much higher adsorption for Cu (II) ions than Zn (II) ions. And the adsorption kinetics and equilibrium adsorption isotherm were further studied.
