摘要
研究了负载三正辛胺泡沫塑料振荡富集发射光谱测定化探样品中痕量金、铂、钯的方法, 并对方法的准确度、精密度、检出限作了相应的讨论。实验表明,该方法同时测定金、铂、钯,准确度 高,精密度好(RSD为5.8%～19.7%),检出限(ng/g)为Au0.5,Pt1.0,Pd1.5。该方法可以满足地 质化探样品的分析测定要求。
The paper studies the determination of trace Au,Pt and Pd in geochemical exploration samples using spectrometric method after being enriched by tri-n-octylamine foam plastic,and discusses the accuracy,precision degree and detection limit (DL).Experimental result shows that the method has high accuracy and precision degree when it is used to determine Au,Pt and Pd simultaneously.The RSD of the method is in the range of 5.8%～19.7%,and the DL of Au,Pt and Pd are 0.5ng/g,1.0ng/g and 1.5ng/g respectively.Therefore,the method can meet the requirement of geochemical exploration sample analysis.
