Simultaneous Determination of Arsenic and Antimony in Steel by Double Channel Atomic Fluorescence Spectrometry with Hydride Generation Technique

A analytical method was proposed for simultaneous determination of arsenic and antimony in steel by hydride generation double channel atomic fluorescence spectrometry. Under optimized conditions, the determination limits of arsenic and antimony were 0.012 ng/g and 0.034 ng/g, respectively. RSD were 1.24％ and 1.97％. The experiment of spiked recovery was carried out in order to validate the method. The recovery was from 96% to 98% for arsenic, 98% to 102% for antimony.
