摘要
应用电感耦合等离子体原子发射光谱(ICP-AES)法对球化剂中镧、铈、钇进行测定,通过硝酸、氢氟酸和盐酸分解试料,高氯酸冒烟驱走硅和氟,最后用盐酸溶解盐类,能准确、快速地测定其含量,加标回收率在97%~100%,精密度实验取得了满意的结果。
The sample was dissolved with nitric acid, hydrofluoric acid and hydrochloric acid, and processed with perchloric acid to remove silicon and fluorine, then the salts were dissolved by hydrochloric acid. Determination of lanthanum, cerium, yttrium in nodulizer by inductively coupled plasma atomic emission spectrometry(ICP-AES) was proposed, the content of the elements could be determined correctly and quickly. The recoveries obtained were in the range of 97% to 100%,the precision of the method was satisfacted.
