| Abstract: |
| A measurement method was studied for simultaneous determination of As, Bi, Cu, Fe, Pb and Se in antimony ingot by using Thermo Electron ICP-OES. The samples were dissolved by sodium tartrate, nitric acid and hydrochloric acid, and were measured directly without separating matrix element antimony. The detection limits of As, Bi, Cu, Fe were good for taking average of multi-wavelength. The results showed that the recoveries of standard addition for these elements are between 96% and 104% . The relative standard deviation was less than 3 %. The results were satisfactory for these elements determination in antimony ingot. |
