| Abstract: | The samples were first digested with method of HNO3-HClO4 wet oxidation,and then the AFS-230 E hydride-atomic fluorescence spectrometry(AFS)was used for determination of As and Hg in fish living in the place where Zhang river and Gong river meet.Under the optimum conditions,the reagent blank’ detection limit of As and Hg were 0.020,0.008 μg/L,the standard solution’average results were 0.099,0.103 μg/mL by six continuous determinations,RSD were 2.64%,4.31%,recovery were respectively 95.9%~101.8%,97.1%~104.0%.This method has advantages of small volume incoming sample,high sensitivity,less disturbance,simple and rapid etc. |
