火焰原子吸收法连续测定氧化锑中铅、铜、铁含量

Dertermination of Lead, Iron and Copper in Antimony Oxide by FAAS

确立了火焰原子吸收测定氧化锑中铅、铜、铁含量的方法,探讨了样品的前处理、酸度、及共存元素的干扰情况,确定了各元素测定的最佳条件,回收率在95.4％-112.1％之间,精密度RSD%不大于5.9％,该方法能满足氧化锑中铅、铜、铁元素的测定。

Lead, Iron and Copper in antimony oxide were determined by FAAS. The method of dealing with the antimony oxide sample and the best determination conditions were studied by IF. Influences of acidity and elements interference were discussed. The rates of recovery of the three elements were from 95.4 % to 112.1 %, and the relative standard deviation (RSD) was less than 5.8%, The results were entirely satisfactory for antimony oxide.
