摘要
介绍用偶氮氯膦Ⅲ特效显色剂进行稀土总量测定的实验方法。实验结果表明,制定的分析方法不但可作炉前快速分析,也可作成品炉后分析,分析误差满足国标GB223.49—85要求。
This paper introduces an experimental method of measuring the total amount of rare earth element through extraordinary effective developer-CPAⅢ. The test result shows the method of analysis laid down can be used not only for quickly analysis before furnace,but also for finished products analysis after furnace. The error in analysis can satisfy the requirement of international standard GB223.49-85.
