摘要
探讨了用离子交换分离富集极谱法测定岩矿样品中的痕量金的方法。在最佳试验条件下金的回收率在93%~103%之间;其相对标准偏差为3.7%。
The method to determine trace gold in rock salt samples with ion exchange separation and enrichment is approached.Under optimum experimental condiction,recovery rate of gold ranges from 93% to 130% and relative standard deviation is 3.7%.
