THE STUDIES ON CHELATING FIBER V．ADSORPTION BEHAVIOR OF Au^3＋ ONTO CHELATING FIBER CONTAINING AMIDOXIME GROUPS

摘要

The adsorption behavior of ionic gold onto chelating fiber containing amidoxime groups was investigated. The chelating fiber presents high adsorption capacity for ionic gold Au^3+（up to 626mg/g,when the content of amidoxime group reaches 7.59mmol/g),and possesses the ability to reduce the Au^3+ into metallic gold,In the redox process,the amidoxime group is oxidized into carboxyl group.
