Abstract

Trace As and Se were determined by hydride generation atomic fluorescence spectrometry in water. This method was simple, rapid and sensitive. The detection limits of this method were: As 0.051 8 μg/L and Se 0.052 4 μg/L. The relative standard deviation was 0.36% ～ 0.62% (n=11), and the recovery was 95.9% ～ 103.7%. The method has been used to determine As And Se in running water, land-surface water and source water.
