| Abstract: |
| In this study, an inductively coupled plasma optical emission spectrometric method for determining beryllium in beryllium associated uranium ore was established. Matrix interference from potassium pyrosulfate, which was added to the digestion solution with alkali fusion and acid dissolution, was investigated, and measures to eliminate the matrix interference were discussed. The results showed that sample weight, potassium pyrosulfate adding amount, constant volume and dilution ratio should be control to effectively eliminate the matrix interference. The relative standard deviation was 3.4%(n=6) . The recovery was 98.7%~104.4%. The proposed method is reliable, accurate, and has been proved by practical application. |
