| Abstract: |
| 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 dissolved by hydrochloric acid.Determination of lanthanum,cerium,yttrium in nodulizer by the method of 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. |
