Arsenic compounds are highly toxic and the toxicity of trivalent arsenic compounds is more powerful than others. There are many ways of its determination. This article describes the determination of trace Arsenic in Qin River by Paper Absorption Spectrophotometry. The result indicate that the limit of detection of this method is 0.001 mg/L, the standard deviation is 0.0007 mg/L and the mark-on recovery ranged from 95.0%~105.6%. Meanwhile, several problems needing attention about experiment process are posed in this paper.
