Abstract:

Due to excellent physical and chemical properties, precious metals are widely used in various fields of national economy and national defense construction, and are extremely important economic and strategic resources. In recent years, due to the rapid growth in the demand for rare and precious metals, the contradiction between supply and demand has become increasingly serious. Therefore, it is very important to selective recovery of precious metals from secondary resources such as electronic waste with high precious metal content. Ion-imprinted polymers (IIPs) are widely used in solid phase extraction, preconcentration, water treatment, membrane separation and electrochemical sensors due to the advantages of simple preparation, cavity fixation, structural stability, good environmental adaptability, high regeneration capacity and selectivity for template ions. In this paper, the research progress of ion imprinting technology in the recovery of precious metals at home and abroad in recent years is reviewed, the preparation process and its application are introduced, and the current problems and future development directions of precious metal ion imprinting technology are analyzed and prospected.

Key words: Precious metals, Ion-imprinted, Selectivity, Recovery, Adsorption
