摘要
在５％～４０％王水介质中，用磷酸三丁酯（ＴＢＰ）－醋酸纤维吸附富集Ａｕ，被吸附的Ａｕ用热硫脲溶液解脱，火焰原子吸收法测定。Ａｕ的回收率大于９８％，方法简便快速，经地质标样分析验证结果可靠。
In the medium of 5%～40% aqua reiga, gold is sbsorbed on tributyl phosphate(TBP)-aceticcellulose.The absorbed gold is eluted with hot thiourea solution and then determined by FAAS.Recovery of >98% is obtained. The method is simple and rapid, and has been applied to the deteimination of trace gold in rocks and minerals with satisfactory results.
