| 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. |
