摘　　要：利用氢化物发生-原子荧光光谱法(HG-AFS)测定浆层纸中的铅含量。研究了实验条件对荧光强度的影响和共存元素的干扰。方法的检测限为0.031μg/ml,精密度为3.87%,回收率为96.6%-101.4%。此方法的操作简单,灵敏度高。The content of lead in coated paper was determined by hydride-generation atomic fluorescence spectrometry （HG- AFS）. The effects of experimental conditions on fluorescence signal intensity and interference from coexisting ions were studied. The detection limit by the method was 0.031μg/ml with relative standard deviation of 3.87 % and rate of recovery of 96.6 % - 101.4%. The method had the advantages of simple operation and high sensitivity.
