| Abstract: | To study the method to detect trace arsenic and mercury in sea water in the same time with dual channel atomic fluorescence. Under test condition, the relative standard deviation was less 4.0% , sample recovery rate was between 92.0% - 104%. This method was simple, sensitive and fast, and was suitable for detection of arsenic and mercury in water. |
