Abstract
Selenium in natural mineral water for drinking is determined by the hydride generation-atomic fluorescence spectrometry.The medium of solution and measurement condition are optimized.Being simple,rapid and highly sensitive,the method is featured by the detection limit of 0.0015 mg/L and the relative standard deviation less than 8.6%.It has been applied to the determination of selenium in natural mineral water for drinking with satisfactory results.
