| 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 aluminium, calcium, barium in inoculants 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 98% to 103%,the precision of the method and the contrast of analytical results were satisfacted. |
