摘要
文中介绍了一个灵敏度高、空白值低的测定地球化学勘探样品中超痕量铑、铱的分析方法,并讨论了主要试剂条件的影响。经过几千件地球化学勘探样品检验,方法可靠,易于操作。该方法采用一般实验室常规设备,能满足1∶20万化探样品对铂族元素分析技术的要求。
The paper introduces a method of analyzing ultra trace rhodium and iridium in geochemical exploration sample, which has high sensitivity and low space value. The paper discusses the influence of the main reagent on the analysis. Tests of thousands of geochemical exploration samples show that this method is reliable and simple. Using conventional laboratory devices, the method can meet the requirement of analyzing platinum family element with 1 ： 200000 geochemical exploration samples.
