| Abstract: | Determination of trace arsenic in natural and waste water samples by hydride generation-atomic fluorescence spectrometry was described. The optimum condition of determination was discussed. The linear range of determination was from Ing/mL to 100ng/mL, the detection limit was 0.25ng/mL and recovery rate was 96% - 108%. The relative standard deviation of 12 determinations of solutions containing 0.5ng/mL arsenic was 1.9%. |
