摘要
该文介绍了预处理中子活化分析方法(PNAA),并测定了铬铁矿石和含矿纯橄岩中的痕量稀土元素。同时还介绍了本次工作质量监控方法及DZ∑-1监控样的分析结果,分析值与推荐值吻合。
The pretreatment with neutron activation analysis is used for determination of trace rareearth elements in chromite and mineralized dunite. The results, the analytical quality and the limit ofdetection are discussed. The results of rock standard sample DZ∑-1 are in agreement with the valuesrecommended.
