Abstract: The invention provides an EDTA (Ethylene Diamine Tetraacetic Acid)-Ni molecularly imprinted material as well as a preparation method and application thereof. The EDTA-Ni molecularly imprinted materialis prepared by adopting EDTA-Ni as a template molecule and beta-cyclodextrin as a monomer under the action of a crosslinking agent. The EDTA-Ni molecularly imprinted material prepared by the technical scheme of the invention has high selectivity and can effectively remove low-concentration EDTA-Ni in nickel plating wastewater, and has the characteristics of high selectivity, fast adsorption, highreusability and the like, and shows a good application prospect. The material can realize efficient removal of low-concentration complex nickel and is expectedly to solve the problems that the traditional nickel removal agent is difficult to deal with and regenerate and a heavy metal capture agent is expensive.
