Determination of Trace Mercury by Hydride Generation Atomic Absorption Spectrophotometry after Cloud Point Extraction

Yanli Wang

Abstract

The method for the determination of trace mercury in water samples by hydride generation atomic absorption spectrophotometry after cloud point extraction was proposed.The effects of pH,concentration of surfactant,and equilibrium time on cloud point extraction were discussed.The enhancement factor of 20 and the detection limit of 0.039 μg/L were obtained for mercury with relative standard deviation of 4.8%(n=11).
