| Abstract: | A flow injection system involving hydride generation was associated with ICP - AES for the determination of arsenic in the environmental samples. The determination conditions and interferential factors had also been studied. Under the optimum experimental conditions, the detection limit was 0.0002 mg/ L, the relative standard deviation of detection results was 1.25%. A several certified reference materials were determined with reliable results. |
