摘　　要：样品用1+1王水分解,在王水介质中,用泡沫塑料吸附金。在本单位定制水浴设备内进行水浴加热溶解,以1%硫脲-盐酸络合解脱金。在石墨炉原子吸收光谱仪上,采用自动进样方式测定金。经国家一级分析标准样品验证,结果与标准值相符。The sample was decomposed with 1 ＋ 1 aqua regia, in which gold was soaked with foam. With water bath heating dissolved in water bath equipment that it was customized by the First Geological Survey of Jilin Province, released gold with 1% thiourea- hydrochloric acid complexing. And then in the graphite furnace atomic absorption spectrometer,determine of gold by autoinjection method. The method has been proved in geological standard reference samples and the results are in good agreement with certified values.
