摘要
试样经650℃灼烧,王水(1+1)冷浸泡分解试样,利用泡沫塑料富集金,采用硫脲溶液解脱金,用火焰原子吸收光谱法测定矿样中的金,本法适用岩石矿物中0.05×10-9以上金的测定。
After the sample is ignited in 650℃ and cold digested in aqua regia （1＋1）,gold is enriched by foamed plastics and is released by thiourea solution.The gold in the sample ore is measured by flame atomic absorption spectroscopy.This method is suit for measurement of gold in rock minerals which contains more than 0.05×10-6 gold.
