| 摘 要： | 建立了超声波辅助浸提-冷原子吸收光谱法测定化妆品中汞的方法,对样品前处理方法、样品取样量、盐酸羟胺、正辛醇及其他共存金属离子等影响因素进行了研究。该方法汞的检出限为0.012μg,加标回收率为87.5%—98.3%,该方法与国标方法对照,缩短了样品前处理时间且结果无显著性差异,为化妆品中汞的检测与质量控制提供了一种快速、准确的分析方法。

| Abstract: | A method of determination of mercury in cosmetics by cold atomic absorption spectrometry with ultrasonic wave assisted extraction was established.The influence factors such as the methods of sample pretreatment,sampling amount,hydroxylamine hydrochloride and n-octanol,other coexistent metal element ions were discussed.The detection limit of mercury in the method is 0.012μg.The recovery of standard addition is 87.5%—98.3%.This method can shorten the sample pretreatment time and the results were not significant difference compared with the national standard method.It provides a rapid and accurate analytical method for detection and quality control of mercury in cosmetics. |
