摘要
应用氢化物发生-原子荧光光谱法（HG-AFS）测定了化妆品中痕量铅，采用高氯酸作为反应介质，并对最佳分析条件进行了探讨。结果表明，该法的检出限为0．5μg／L，线性范围为1．00～400μg／L，回收率为88．7％～96．5％。用标准物质进行对照，测定值均在规定的标准值范围内。该方法操作简便，精密度和准确度好，线性范围宽，检出限低，具有实际应用价值。
A method for determining the content of lead in cosmetics by hydride generation-atomic fluorescence spectrometry （HG-AFS） was studied. The optimal analytical conditions in perchloric acid medium were discussed. The detection limit is 0.5 μg/L, the linear range is 1.00～400 μg/L, and the recovery is about 88. 7%～ 96. 5%. The experiment results showed that this method had many advantages and was applicable for the detection of lead in sapmles.
