| Abstract: |
| The contents of Tl in Lead-Zinc concentrate samples were determined by ICP-AES after the samples were dissolved in nitric acid, hydrochloric acid, hydrofluoric acid and perchloric acid and the solution was diluted. The measurement range was from 0.005% to 0.05%. By experiments, the appropriate solution acidity and the correction method for interference elements were determined. The relative standard deviations(n=7) were between 1.3% and 4.8%, and the recoveries were in the range from 93.7% to 102%. ?Due to less interference, fast speed and accuracy, the method is applicable for the determination of Tl concentration for the batch samples of Lead-Zinc concentrate. |
