聚氯化铝中的砷和汞

Abstract

Abstract: Application of hydride generation-atomic fluorescence spectrometry method in the simultaneous determination of arsenic and mercury in polyaluminium chloride used for drinking water was studied.This method is of high sensitivity and good accuracy.Under optimal conditions，the potassium borohydride concentration，detection limit，precision，and recovery rate were investigated.Results showed:the detection limits of arsenic and mercury were 0.007 9 μg/L and 0.002 6 g/L， respectively：the recovery rates of arsenic and mercury were 93.75%~103.83% and 105.00%~108.75%，respectively.

Key words: hydride generation-atomic fluorescence spectrometry, polyaluminium chloride, arsenic, mercury
