摘　　要：本文以聚氨酯泡沫塑料为载体,采用负载一定量的磷酸三丁酷(TBP)预处理、吸附、洗涤、灰化、装样摄谱6个步骤,可以有效解决一些实验室化探样品中痕量金测定问题,其方法具有检出限低,成本低。通过对国家化探级标准物质进行分析测定,表明该方法具有较好的精密度和准确度,能满足化探痕量金的测定。By adopting this process with polyurethane foam plastic loaded with certain amount of tributyl phosphate pretreatment, adsorption, washing, ashing, loading and spectrography, the analyzed procedure can solve the problem of the determination of trace gold in geochemical exploration samples. This method can decrease the cost and had low detection limit. Base on the measuring national standard substance, it indicated that the method had high accuracy and precision, so the procedure can satisfy the need of trace gold in geochemical exploration samples.
