| Abstract: | In this paper, the method on the AFS - 930 atomic fluorescence Spectrome - ter for determination of trace arsenic （As） and selenium （Se） in water was studied. The water sample was treated by 10 %HCL and 10 % Thiourea - 10 Ascorbicacid. The method is based on the reaction of arsenic （As） and selenium （Se） with KBH4 to form the hydride gas in medium of 5 % HCl. The detection limits are： As 0.20 μg/L Se： 0.13 μg/L. The method is simple, rapid, less, matrix interference and high sensitivity It can be applied to simultaneous determination of As and Se in the industrial wastewater. |
