本文使用 LZ-1200型流动注射氢化物发生器与 WFX-1D 型原子吸收分光光度计联用测定了化妆品中痕量砷。分析速度160样/h,待测试样消耗量400μl,测定含量水平为10μg/L 砷的相对标准偏差为1.3%(n=11),方法检出限为0.3μg/L,测定化妆品中砷的回收率在92.0～101.3%。
In this paper, LZ-1200 flow injection hydride generator with WFX-1D atomic absorption spectrophotometer for the determination of trace amounts of arsenic in cosmetics. The relative standard deviation (RSD) was 1.3% (n = 11) and the detection limit was 0.3μg / L. The determination of arsenic in cosmetics The recovery rate was 92.0 ~ 101.3%.
