The production technology for amidoxime chelate fiber was introduced, as were the chelating mechanism of the interaction between the fiber and metal ions, adsorption isotherm and the influential factors on the adsorption reaction. The application of amidoxime chelate fiber was summarized in the fields of metal ion extraction and waste water treatment and purification. The research progress in the coordinate complexes of amidoxime fiber and metal ion was reviewed in the fields of ion exchange and adsorption material, antibacterial fiber and catalyst. The development trend of amidoxime chelate fiber was outlooked. It was pointed out that rational choice of a crosslinker be the key to produce amidoxime chelate fiber with favorable mechanical properties.
