The analytical method of hydride generation-atomic fluorescence spectrometry was established to determine the contents of mercury and arsenic. Mercury and arsenic had good linearity with r > 0. 99 for both elements. And this method had low detection limits and high precision. The accuracy of the method was confirmed by recovery tests. The results showed that the recoveries of both elements were in the range of 93. 6% -107% , which accorded with requirement of recoveries. And the contents of mercury and arsenic in water samples,which were tested by the established method,accorded with the National standard values.
