A method for the determination of lead in aluminium polychlorid by continuous flow-hydride generation atomic fluorescence spectrometry was established .The effect of experimental conditions on the atomic fluorescence intensity were investigated and optimized .In this condition ,the calibration curve was linear up to 25μg/L ,the detection limit was 0 .043μg/L ,and the recovery was in range of 95 .3%-105.6% . The method is not only simple and rapid but also precise and accurate ,and shows good application pros-pects .
