Rapid Determination of Micro Amount of Gold in Field Geological Samples

摘要: 介绍了稀王水冷浸取，硫代米虫酮显色，以聚丙烯滤棒为载体，一次完成富集、显色的野外测定微量金的方法。对实际金矿样品进行测定，精密度（RSD，n=10）＜6％；对国家级标准物质进行测定，结果与标准值相符

Abstract: A colorimetric method for rapid determination of micro amount of gold in field geological samples was reported in this paper. Aqua regia was used to decompose the sample. Polypropylene filter rod was used as gold adsorbent and TMK as color reagent, so th
