Preparation of Surface Imprinted Polymer D301-g-IIPDMC and its Recognition Selectivity Performance towards AuCl4−

In this article, a new surface imprinted polymer D301- g -IIPDMC is successfully prepared using AuCl 4 − as a template. The adsorption and recognition performances of D301- g -IIPDMC for AuCl 4 − are studied by using a static method and competitive adsorption experiment. The experimental results show that D301- g -IIPDMC possesses very strong adsorption affinity and excellent recognition for AuCl 4 − . The adsorption capacity of D301- g -IIPDMC for AuCl 4 − is 831.08 mg/g, and the selectivity coefficient relative to CuCl 4 2− is 128. The adsorption behavior is an endothermic spontaneous process, and fit well with pseudo-second order kinetic model and Freundlich adsorption isotherm model. Besides, D301- g -IIPDMC is desorbed easily and exhibits excellent reusability.
