摘要

Abstract

Inverse emulsion polymerization was employed to synthesize inverse emulsion Cd(Ⅱ) imprinted polymers (IEⅡ P). The morphology and functional groups of IEⅡP were characterized by SEM

FTIR and TG. Static adsorption experiments and competitive adsorption test were used to evaluate the adsorption ability of IEⅡP. The adsorption capacity of polymers could reach 86.7 mg·g

-1

under the optimal adsorption conditions. The pseudo second order kinetic model and Langmuir isotherm model could be used to analyze the experimental data well. The adsorption process of IEⅡP was chemical adsorption process and monomolecular type. Thermodynamic parameters showed that the adsorption process was endothermic and could occur spontaneously. The selectivity coefficients k of Cd

/Zn

and Cd

/Cu

were 2.4998

1.2437 and 4.6882

respectively. The proposed method provides a new thought for removing Cd(Ⅱ) in water samples.
