摘要: 建立了一种测定化妆品粉质原料中Pb,Hg,As和Cd 4种重金属元素的湿式消解-氢化物发生原子荧光光谱法。通过比较湿式消解法和干灰化法的加标回收率,结果显示,湿式消解法更适合4种重金属元素的前处理。在较优的实验条件下,湿式消解-氢化物发生原子荧光光谱法测定Pb,Hg,As和Cd的线性范围分别为0~16.0,0~1.6,0~16.0和0~1.6 μg/L,相关系数(R2)为0.993 5~0.999 7,方法检出限为0.036~0.768 μg/L,样品加标回收率为81.0%~93.0%。该方法灵敏度高,精密度和准确度好,满足分析要求。同时利用该方法实际检测了10种化妆品粉质原料。

Abstract: A detection method of lead,mercury,arsenic and cadmium in powder form raw materials used for cosmetics was established by hydride generation atomic fluorescence spectrometry with wet digestion method as the sample pretreatment.Comparison of spiked recoveries of wet digestion method and dry calcination method showed that the wet digestion method is more suitable for sample preparation.Under the optimized conditions,the linearity range of lead,mercury,arsenic and cadmium are 0-16.0,0-1.6,0-16.0 and 0-1.6 μg/L respectively.The correlation coefficients (R2) are from 0.993 5 to 0.999 7;the detection limits are from 0.036 to 0.768 μg/L;the spiked recoveries are from 81.0% to 93.0%.The method is sensitive,accurate and precise for the detection of heavy metals and has been successfully applied to detect lead,mercury,arsenic and cadmium in 10 kinds of powder form raw material used for preparation of cosmetics.
