Three new aromatic amidoxime organic compounds including o methyl benzamidoxime (OBH), m methyl benzamidoxime (MBH) and p methyl benzamidoxime (PBH) were synthesized and characterized, whose collecting effects on oxide ores such as wolframite, scheelite and fluorite associated with structure and activity relationship were also investigated.

A functional material for chelating separation with amidoxime group, is often used in heavy mental ions' (including Uranium, Thorium, rare mental) absorption and enrichment, radiochemical separation and radiochemical waste water disposal.

Amidoxime functionalized fiber was prepared by reacting polyacrylonitrile fiber with hydroxylamine, resulting from that nitrile group was transformed into amidoxime group.

The treatment of Cu－coating waste water with recoverable modified PAN fiber containing amidoxime group;
