氢化物发生原子荧光光谱法测定膏类化妆品中的砷

选择适当的化妆品前处理方法，应用氢化物发生原子荧光光谱法对膏类化妆品中的砷进行测定。当曲线的浓度处于0-50 ug·L^-1时，砷的浓度与荧光强度呈良好的线性关系，相关系数可达到0.9999。RSD小于4.67%。加标回收率处于92.4%-97.6%。方法线性范围宽，简便快速，稳定性好，灵敏度高，可广泛应用于膏类化妆品中砷的测定。实验中进一步优化实验条件，得到了准确的测定结果，保证回收率。

The Detection of Arsenic in Poultice Cosmetic and Foodstuff by Hydride Atomic Fluorescence Spectrometry

Choosing appropriate pre-digestion method to cosmetic, detecting Arsenic in poultice cosmetic and foodstuff by hydride atomic fluorescence spectrometry was applied. Concentration of arsenic and fluorescence intensity have nicer linear when the concentration of standard curve was between 0-50 ug·L^-1 , the related coefficient in this scope could reach 0. 9999,RSD under 4. 67%. The added recovery rate was between 92. 4% and 97. 6%. Method was simple and fast,it with high intelligent degree,good stability and nice linearity scope,it was far-ranging applied in detection of Arsenic in the poultice cosmetic. The condition of experiment was optimized;we could receive exact result and assure the added recovery rate.
