A method for determination of lead in spirits by hydride generation-atomic fluorescence spectrometry was established. The infection factors were studied, and the best test conditions were selected. The linearity range for the determination of lead was 0-20.0 μg/L, and the limit of detection was 1.0 μg/L. The recoveries were in the rang of 94.0%-108.0%. The relative standard deviations were 3.28%-4.03%(n=11).
