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%.
摘要
介绍了用电感耦合等离子体原子发射光谱法（ICP-AES）直接测定锑产品中砷、铜、铁、铅和硒的方法。我们选择了折衷条件来测定砷、铜、铁、铅和硒，并讨论了基体浓度的影响。检测限为0.028 - 0.327微克·毫升⁻¹，回收率为94.0% - 107.1%，相对标准偏差小于5%。
