随着黄金地质找矿工作的迅速发展,为了研究金矿成矿规律,研究金矿的物质来源,寻找盲矿体,1975年底全国冶金黄金地质科研会议上要求解决矿石、岩石中痕量金的分析方法(灵敏度高于或近于金在地壳中的平均含量,5 × 10~(-7)％克),然而,我国当前常用在金矿分析上的比色法、容量法是难以解决的。由于催化比色法具有灵敏度高、准确性好的特点,近年来广泛地被应用在痕量元素的分析上。金和其他贵金属元素一样
With the rapid development of gold geological prospecting work, in order to study the law of gold mineralization, study the material source of the gold mine and search for the blind ore body, at the end of 1975, the National Metallurgical Gold Geology Conference requested to solve the problem of trace gold However, the current colorimetric method commonly used in gold analysis in our country, the volumetric method is difficult to solve . Due to the high sensitivity and good accuracy of catalytic colorimetric method, it has been widely used in the analysis of trace elements in recent years. Gold is the same as other precious metal elements
