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

[摘要] In this article, a new surface imprinted polymer D301‐g‐IIPDMC is successfully prepared using AuCl4− as a template. The adsorption and recognition performances of D301‐g‐IIPDMC for AuCl4− 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 AuCl4−. The adsorption capacity of D301‐g‐IIPDMC for AuCl4− is 831.08 mg/g, and the selectivity coefficient relative to CuCl42− 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.
