| Abstract: | Determination of total arsenic in city 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 5 ng/mL to 50 ng/mL,recovery rate was 100%~103%,the residual standard deviation of six specification curves was 1.3 and the detection limit was 0.26 ng/mL. The method can be used to assay total arsenic in other different water samples. |
