摘　　要：重点研究了镨钕配分对测定镨钕中镧、铈、钐、钇、铝、硅量的影响。通过研究镨钕配分与其空白值之间的关系,采用一定校正方法,成功地用一套标样解决了不同镨钕配分试样中的镧、铈、钐、钇、铝和硅量的测定问题。方法简单易行,结果稳定可靠。与ICP-M S的对照结果令人满意。By means of base matching method to detect lanthanum, cerium, samarium, yttrium, aluminum, silicon in Pr--Nd compound. It is difficult to detect the elements when the content of the Pr,Nd changed. The paper mainly discussed the effect of Pr,Nd distribution on the detecting results of lanthanum, cerium, samarium, yttrium, aluminum and silicon. By certain calibration method, this detecting method successfully detects the amount of lanthanum, cerium, samarium, yttrium, aluminum and silicon in different contents of Pr and Nd. And the results are satisfied in comparison with the ICP--MS method.
