Abstract:
The direct determination of As, Cu, Fe, Pb and Se in antimony products with ICP-AES is presented. We selected compromise condition to determine of As, Cu, Fe, Pb and Se and the influence of matrix concentration is discussed. The detection limits are 0.028-0.327 microgram.mL-1 and the rates of recovery are 94.0%-107.1% and RSD are less than 5%.
