本文探讨了用微型活性碳柱富集痕量金的方法。研究了富集金和TMK—Au—Twee 85显色反应的条件,用本法测定了地质试样中痕量金,其测定限为2 ppbAu,本法操作简便、快速,灵敏度高,结果较为满意。
This article discusses the use of micro-activated carbon column enrichment of trace gold method. The conditions for the color reaction of gold and TMK-Au-Twee 85 were studied. The method was applied to the determination of trace gold in geological samples with a limit of determination of 2 ppb Au. The method is simple, rapid and sensitive. satisfaction.
