Under different pH conditions,the trace concentrations of total arsenic and arsenite in synthesized waster-water samples were determined by hydride generation coupled with atomic absorption spectrometer(HG-AAS).The limit detection of total arsenic and arsenite were 0.067μg/L and 0.395μg/L,and Beer’s law was obeyed in a wide linear dynamic range of 0.067μg/L-20μg/L and 0.395μg/L-20μg/L *** recovery of total arsenic and arsenite was 97.7%-99.9% and 89.4%-106%,respectively.
