Abstract
Mercury content is an important toxicological index in drinking water.After digestion in acid and reduced by NaBH_(4),mercury can be surveyed by atomic fluorescence spectrometry(AFS).The detection limits is 1.1×10~(-3) μg/ L,linear range is 1.2×10~(-2)μg/L~1.20 μg/L,RSD is 6.3 %,the recovery is in the range of 87.6 %~112.5 %.
