| Abstract: |
| A method for determination of antimony elements in insoluble lead?concentrate by ICP-AES was established in this article. For the samples, which were difficult to be dissolved, nitric acid, sulfuric acid and tartaric acid were determined to be used for sample dissolution treatment and the optimal conditions for sample dissolution were also found. The results indicated that the detection limit of antimony elements was 0.005 μg/mL，with the recoveries of 99.0%~102% and the relative standard deviations of 1.5%~3.2%. The method is precise and rapid so that it can be used in the determination of antimony elements in insoluble lead?concentrate. |
