摘要
含金氰化液经王水处理后,在一定酸度下,用磷酸三丁酯醋酸纤维富集金,以氢醌滴定法进行测定,金的吸附率高达98.5%以上,吸附容量为13mg/g磷酸三丁酯醋酸纤维。该方法测定金的相对标准偏差为2.47%,可以满足生产工艺要求。
Firstly, cyanide solution containing gold is handled by aqua regia. Secondly, gold is enriched with tributyl phosphate (TBP)-acetic cellulose in a certain acidity. Finally, gold is determined by the titrimetric method of hydrogen quinine. The adsorption rate of gold is higher than 98.5%, the adsorption capacity of single pilla is 10 milligrams. The determination relative standard deviation of this method is 2.47% ,and it can satisfy the production process requirement .
