Abstract: The adsorption behavior of Au(Ⅲ) ion onto the chelating fiber containing amidoxime group was investigated, and the factors to influence the adsorption capacity were discussed.The chelating fiber presents a high adsorption capacity to Au(Ⅲ) ion, and is able to reduce the adsorbed Au(Ⅲ) ion into metallic gold.In the solution containing Au(Ⅲ),Cu(Ⅱ),Zn(Ⅱ) and Cr(Ⅲ), the fiber presents a high selectivity to Au(Ⅲ).With increasing amidoxime group content in the fiber, temperature and initial concentration of Au(Ⅲ) ion, the adsorption rate and capacity increase.

Key words: Chelating fiber, Amidoxime group, Au(Ⅲ) ion.Adsorption selectivity, Metallic gold
