摘　　要：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 respective.The recovery of total arsenic and arsenite was 97.7%-99.9% and 89.4%-106%,respectively.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. 395μgg/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 respective. The recovery of total arsenic and arsenite was 97.7% - 99. 9% and 89. 4% - 106%, respectively.
