摘要
采用HNO3-H2O2消化样品,用氢化物发生原子荧光光谱法测定彩妆类化妆品中汞的含量。当汞的浓度处于0-10μg/L时,其浓度与原子荧光强度呈良好的线性关系,相关系数为0.9997。回收率为90.65%-98.92%。该方法简便快速,稳定性好,灵敏度高,可广泛应用于彩妆类化妆品中汞的测定。
A method for the determination of mercury in cosmetics by Hydride generation Atomic Fluorescence Spectrometry （HG- AFS） was established. The samples were digested with HNO3 -H2O2. The mercury content was linear with fluorescence intensity in the rate of 0 - 10μg/L and the correlation coefficient was 0. 9997. The recovery rate was 90.65% -98. 92%. The method is simple and rapid. It has good stability, high sensitivity and can be extensively applied to determinate mercury in cosmetics, especially for making -ups.
