摘　　要：贵金属(尤其是铂族金属)属于我国短缺矿种之一;为实现化探方法直接寻找贵金属金、铂、钯等,需要一种操作简便、检出限低、对仪器无特殊要求的分析测定方法。文中研究了在SnC l2存在下,用负载醋酸丁酯的泡沫塑料进行富集,发射光谱分析测定化探样品中痕量金、铂、钯的方法。该方法用于国家级标准样品的测定,结果与推荐值相符合。Precious metal, especially platinum group of metals is rare in China. In order to investigate Au, Pb and Pd with agrochemical methods, a simple determination and analvsis method is needed, which has low DI and has no special requirement to the determination devices. A spect,ometrie method is accepted with foam plastic loaded with butyl acetate to simuhaneously determinate trace Au, Pt and Pd in geochemical sample after separation by foamed plastics loaded with butyl acetate is represented. The optimum conditious for separation were investigated. The ore containing Au, Pt and Pd were analyzed with acceptable recovery.
