建立了冷浸--泡沫塑料富集,采用 ICP-AES 测定地球化学勘探样品中超痕量金、铂、钯的方法,并试验了冷浸取、泡沫塑料富集时各种因素的影响；确定了采用氯化钠、盐酸和高锰酸钾冷浸取分解试样,以泡沫塑料富集、灰化,残渣用王水溶解,用电感耦合等离子体发射光谱法测定的条件。该方法检出限分别为：Au 0.039ng/g,Pt 0.040ng/g,Pd 0.058ng/g；回收率为95.6％~102.5％之间；测量精密度( RSD%)为：Au 4.85％,Pt 5.76％,Pd 6.45％。采用该方法测定了国家一级地球化学标准物质中的痕量 Au,Pt,Pd,测定值与标准值符合规范要求。

In this paper, we set up the enrichment of cold soaking foam plastics by adopting the method of ICP-AES to test the ultra-trace of gold, platinum and palladium from the geochemical exploration sample and studied all kinds of effective factors in cold soaking foam plastics enrichment. And we confirmed the requirements of using sodi-um chloride, hydrochloric acid and potassium permanganate cold soak-ing to decompose the sample, using foam plastics to enrich and ash, aqua regia to dissolve residue, and measuring by inductive coupling Plasma Atomic Emission Spectrometry. The detection limits of this method are as follows: detection limit: Au 0.039ng/g, Pt 0.040ng/g, Pd 0.058ng/g; recovery rate: between 95.9% and 102.2%; relative stan-dard deviation (RSD%): Au 4.85%,Pt 5.76%,Pd 6.45%.We tested the trace amount of Au, Pt and Pd in the country-level geochemistry stan-dard substance. The measured value is consistent with the normalized value.
