研究了含胺基的螯合纤维对三价金离子的吸附行为.结果表明,含二乙胺基和二乙醇胺基的螯合纤维对金离子的吸附量较大,而且吸附快、对金的选择性好,还能将所吸附的金离子还原成单质金.

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 o
