| Abstract: | ICP-MS was adopted to measure Pb, Sn, As, Sb and Bi in low alloy steel. The sample wasdissolved by hydrochloric acid and nitric acid and internal-standard rhodium and iron base were addedto correct the influence of matrix effect on the result. 75As, 118Sn, 121Sb, 208Pb and 209Bi were chosen as isotope for measuring elements. A simple and fast method of analyzing five harmful elements in low alloysteel was established. With short analyzing cycle, strong sensitivity, high precision and good anti-interference ability, this method is simple, practical and accurate and can be applied to analysis on low alloysteel samples in scientific research and production. |
