Abstract

Belonging to the fields of electroactive functional polymer film material preparation and selective separation of ions, the invention relates to a preparation method of an ion imprinted polymer film. The invention is characterized by relating to a preparation method of an ion imprinted polymer film with an electronic control cation exchange function. The method includes: preparing a water solution of the monomer for polymer preparation, an electrolyte solution, a protonic acid solution, an imprinted ion solution and a doping ion solution, then mixing the five solutions, conducting in situ polymerization on a conductive substrate by a monopolar pulse electrodeposition method so as to synthesize imprinted ion removed ferricyanic group doped polymer film by one step. Being simple and fast to operate, the method provided in the invention needs no additional pickling step and can realize imprinted ion removal in situ. Also, the preparation conditions are mild and are easy to control. The ion imprinted polymer film prepared by the method has an electronic control cation exchange function, and can be used for selective removal of heavy metal ions in water or separation recycling of rare earth ions.

Description

technical field [0001] The invention discloses a method for preparing an ion-imprinted polymer film, which belongs to the field of preparation of electroactive functional polymer film materials and the selective separation of ions, and specifically relates to a method for preparing an ion-imprinted polymer film with an electronically controlled cation exchange function. Background technique [0002] Heavy metal ion pollution has become a serious problem worldwide that threatens the environment and human health. On the other hand, these heavy metal ions, including noble metals and rare earth ions, are important strategic resources. Therefore, the separation and recovery of heavy metal ions is important in both environment and resources Is of great significance. However, conventional treatment methods such as chemical precipitation, adsorption, electrolysis and ion exchange are difficult to meet the technical and economic requirements of purification treatment, especially when...
