平台石墨炉原子吸收法测定合金钢中痕量镉

DETERMINATION OF CADMIUM IN STAINLESS STEELS BY PLATFORM GRAPHITE FURNACE AAS

本文研究了平台石墨炉原子吸收法直接测定合金钢中的痕量镉,不需分离,不需加基体改进剂。测定范围为Cd 1μg/g～10μg/g;相对标准偏差为9.0%～14.0%;回收率为98%～102%。

In this paper we studied direct determination of traoe cadmium in stainless steels by platform graphite furnace AAS. Without separating, without adding improving agent of matrix. Detection limit is of 1μg/g to 10μg/g. Relative standard deviation is of 9.3% to 14.3%. Recovery is of 98% to 102%.
