摘要
本文采用泡塑富集化探样品中痕量金,用石墨炉原子吸收法测定痕量金。试样经灼烧,王水密封溶矿,泡塑富集,硫脲解脱等过程进行了改进及条件控制,该方法具有检出限低,灵敏度高,操作简便,速度快,劳动强度小,适用地质化探样品中痕量金的测定。
This paper uses a foam enrichment of trace gold in geochemical samples,using graphite furnace atomic absorption spectrometry determined trace gold.Sample by burning aqua regia soluble mineral sealed,foam enrichment,thiourea relief and other process improvements and conditions of control,this method has low detection limit,high sensitivity,easy operation,speed,labor intensity,determination of trace gold in geological geochemical samples.
