| 摘 要： | 建立了锍镍试金富集—电感耦合等离子质谱法测定地质样品中金铂钯铑铱钌的方法。研究了富集时各种实验因素的影响,样品用琉试金富集,盐酸处理锍镍扣,碲共沉淀富集,过滤,沉淀用王水溶解,ICP-M S测定。方法检出限:A u为0.11、P t为0.050、Pd为0.028、R h为0.018、Ir为0.013、R u为0.02,相对标准偏差(n=12),A u为8.25%、P t为4.76%、P t为4.97%、R h为5.63%、Ir为5.38%、R u为6.81%。经国家一级地球化学标准物质验证,铂族元素和金的测定值与标准质相吻合。

| Abstract: | The determination of gold,platinum,palladium,rhodium,iridium and rutherium in geological samples by sulfonium nickel assaying and ICP-MS testing methods was studied in this paper.The effects of various testing factors when elements enriched have been studied in detail.The six elements were enriched by sulfonium nickel assaying,while sulfonium-nickel button was treated by using HCl.Precious metal co-precipitated with Te element,and the precipitation was dissolved by aqua regia after filtrating,at last the si... |
