痕量稀土元素的分析,国内一般是经萃取富集后在盐酸介质中进行反萃取,然后制成固体样进行光谱测定。本文研究了以PMBP-碳粉载体萃取富集痕量稀土的方法,化学分离操作简便,损失少,精度好。各种稀土元素的测定下限为0.003—0.06微克。
Analysis of trace amounts of rare earth elements, the domestic is generally extracted by enrichment after stripping in hydrochloric acid medium, and then made into a solid sample for spectrometry. In this paper, a method for enrichment of trace rare earth with PMBP-carbon carrier was studied. The chemical separation was simple, less loss and good accuracy. The lower limit of determination of various rare earth elements 0.003-0.06 micrograms.
