摘　　要：介绍断续流动氢化物发生原子荧光法测定高纯三氧化二锑中痕量汞的方法。本法使用酒石酸遮蔽法,防止锑的水解,从而有效的克服了锑的干扰。在优化试验条件下,汞的检出限为0.05 ng/mL,回收率为95%~105%。A method for the determination of mercury in high purity Sb2O3 by the intermittent flow-hydride generation atomic fluorescence spectrometry was described.The method prevent the Sb from hydrolyzing by the defilade of tartaric acid,so as to efficiently conquering interference of Sb.The operation conditions were optimized.The detection limit was 0.05 ng/mL and the recovery was 97 %~105 %.
