摘要
采用连续流动-氢化物发生原子荧光光谱法（CF-HGAFS）测定聚合氯化铝中的铅，优化了实验条件，在最佳实验条件下，铅的荧光强度在0～25μg /L范围内与浓度呈良好的线性关系，方法检出限为0.043μg/L ，方法回收率在95.3％～105.6％之间，本法操作简便、快捷，而且具有很好的准确性和精密度，应用前景良好。
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 .
