CE为主法、测定化探试样中砷等九元素

THE DETERMINATION OF NINE ELEMENTS IN GEOCHEMISTRY PROSPECT SAMPLE BY CE METHOD

选用CE,以碘化铵、沉淀硫、石墨粉为缓冲剂,是多元素分组测定的一种简便快速分析手段,它集中体现目前我国原子发射光谱分析中主要特点和优点。

Combined with the use of NH_4 I, precipitable sulfur and graphite powder as cushion reagents, the CE method is a good analytical method for the determination of easy evaporated multi-elements. The method is simple and rapid, and obtained good results.
