摘　　要：采用氢化物发生-原子荧光光谱法测定驱蚊水中的砷(A s)和汞(Hg)。在0—50.0μg/L范围内砷和汞的浓度与荧光强度呈线性关系,相关系数均为0.9993,加标回收率分别达到99.76%—103.46%和90.10%—100.10%,砷、汞测定结果的RSD分别小于3.9%和6.6%;同时指出了测定时应注意的事项。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.
