摘要
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 paper discusses a method for concentration of trace gold by mic-absorber of active carbon. The optimum conditions for concentration of gold and chromogenic reaction of TMK-Tween 85-Au are studied. The trace gold in the geological sample has been determined with this method, The detection limit is found to be 2ppb for gold. The operation is simple and rapid with high sensitivity, with saris-factory results.
