Abstract

The method for simultaneous determination of arsenic and mercury in insect repellent by hydride generation atomic fluorescence spectrometry(HG-AFS) was studied.There was linear relationship between the concentrations of arsenic and mercury and fluorescence intensity in the range of 0—50.0μg/L with the correlation coefficients both of 0.9993.The recoveries of arsenic and mercury were 99.76%—103.46% and 90.10%—100.10%,respectively,and RSDs of them were less than 3.9% and 6.6%.Attentive matters of the determination were put forward.
