N503浸渍树脂吸萃金的性能及其应用
摘要:
研究了N,N-二仲辛基乙酰胺(N503)浸渍树脂从盐酸溶液中吸萃金的性能和机理。确定了吸萃物分子中金和N503之比为1:2,金以AuCl4-形式被树脂吸萃。吸萃机理属离子缔合反应:2N503+H++AuCl4-=(N503)2·H+·AuCl4-用动态法试验了N503浸渍树脂对金矿石中金的分离。

ADSORPTION OF GOLD BY IMPREGNATED RESIN N503 AND ITS APPLICATION IN ANALYSIS OF GOLD IN ORES
Abstract:
The characteristics and mechanism of the adsorption of gold in hydrochloric acid medium by impregnated resin N503 N,N-di(sec-octyl) acetamide have been studied. The ratio of gold to N503 in the adsorbate is 1:2. IR and chemical analysis show that the gold is adsorbed in form of AuCl4-. The adsorption is an ion association reaction:2N503+H++AuCl4-=(N503)2·H+·AuCl4- Gold in ores has been seperated and determined by N503 satisfactorily.
