Abstract: 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
