ADSORPTION BEHAVIOR OF Au~(3+) ION ONTO THE CHELATING FIBER WITH AMINE GROUP
胺型螯合纤维对Au^3^＋的吸附行为

The chelating fibers with diethanolamine group or diethylamine group present great adsorption capacity, high adsorption rate as well as good selectivity for Au3+ ion. In addition, the adsorbed Au3+ion is reduced into metallic gold by the fibers, and the obtained gold is spongy when the fiber matrix is burnt out.
