| Abstract: | The paper is about a method of concentration of impurity Pb in high purity Tin by way of chlorination to separate the matrix and determination by ICP- MS. After separating matrix Tin by chlorination and using T1 as internal standard, the interference due to the effects of matrix can be corrected efficiently. The detection limit is 0.05 ng/mL;the RSD is 0.8% ～ 1.1% and the recovery of standard addition is 96% - 104%. The method can meet the need of determination of impurity Pb in high purity Tin above 99.999%. |
