摘要
将需测试的样品灼烧后用王水分解,定容之后放置24小时以上,然后取部分澄清溶液,用超纯净水水稀释至总稀释系数的250倍后,采用电感耦合等离子体质谱仪测定其浓度。本方法适用于区域地球化学调查样品、水系沉积物、土壤及岩矿样品中钯、铂元素含量的测定。本方法经标准样品比对和实验室间检验结果的比对验证,其结果准确、可靠,分析流程简便快捷。
The sample is dissolved with aqua regia after ignition,lay aside more than 24 h after volume fixed.Then,take a part of clear solution,dilute with pure water by 250 times of the total dilution coefficient,test the concentration with the inductive coupling plasma mass spectrography. This method is suitable for the testing of Pd,Pt in regional geochemical survey,water system sediment,soil,rock and mineral sample. According to the examination of standaed sample, lab detection, the result of this method is precise, reliable, analysis flow chart simple and rapid.
