摘要
稀土元素的分析主要采用有机试剂萃取。偶氮试剂做为显色剂的比色分析,分析手续繁琐,也不易得到满意的分析结果,本文在EDTA容量法的基础上,采用较为简便的(NH4)2SO4浸取EDTA-Zn滴定法直接测定新型稀土总量,大大简化了试样的分析过程和操作手续。
The colorimetric analysis is the main method for REE testing,by organic reagent extraction and using azo reagent as the chromogenic agent.The analysis process is troublesome and isn't easy to get the satisfactory result.In this paper,basing upon the EDTA capacity method,we use the simpler(NH4)2SO4 leaching EDTA-Zn titration method for the direct testing of new total REE,which can enormously simplify the analysis process and operation.
