| 摘 要： | 利用泡沫塑料对地质样品中微量金进行富集，已经是非常成熟的富集方法。常量金经过泡沫塑料吸附后，用硫脲脱附原子吸收测定也是近几年许多实验室常用的方法。而用等离子体光谱仪测定常量金鲜有报道，该方法简单、快捷，通过对国家一级标样的分析试验，对于金含量为0．05-50．00g／t的样品能够满足要求。

| Abstract: | By using foam plasma, trace gold in geological samples have been enriched. It is already a very mature enrichment method. After foam adsorption of constant gold, using thiourea to desorpt, then determined by using atomic absorption spectrometry is a method commonly used in many laboratories in recent years. While determination of constant gold by using plasma spectrometer has rarely been reported. This method is simple and fast. Through analysis and experiment on country--level standard samples, it is regarded that test can meet the requirements of the samples with gold contents of 0.05-50.00g/t . |
