In recent years, as an important development direction of molecular imprinting technology, ionimprinting technology has become a focus in the field of water heavy metal detection due to its excellent predetermination, identification, and practicability. The principles and development of ion-imprinting technology are introduced mainly in this paper, and the preparation methods of ion-imprinted polymer (IIP) such as bulk polymerization, suspension polymerization, precipitation polymerization and surface imprinting are analyzed and compared. Finally, the application and development of ion-imprinting technology in electrochemical detection of heavy metals in water are reviewed.
