摘要： 建立微波消解-电感耦合等离子体发射光谱(ICP-OES)法同时测定化妆品中砷(As)、铅(Pb)和镉(Cd)。方法采用硝酸-双氧水体系,优化了ICP-OES条件。结果表明,3种重金属元素在0.05~1.20 mg/L范围内呈良好线性关系;As,Pb和Cd的相关系数均为0.999 8,检出限分别为0.63,0.30和0.015 mg/kg,定量限分别为2.1,1.0和0.05 mg/kg,平均加标回收率为90.7%~108.6%,相对标准偏差为0.44%~4.59% (n=6)。

Abstract: A simultaneous determination method for arsenic (As),lead (Pb) and cadmium (Cd) in cosmetics by inductively coupled plasma-optical emission spectrometry (ICP-OES) was established.The sample was digested by nitric acid-hydrogen peroxide under the assistance of microwave irradiation.Meanwhile,the conditions of ICP-OES were optimized.The method under optimized conditions shows good linearity with the mass concentrations of the three heavy metal ions in range of 0.05-1.20 mg/L.The corresponding linear correlation coefficients for the heavy metals are all 0.999 8 with the spiked recoveries ranging within 90.7%-108.6%,and the relative standard deviation within 0.44%-4.59%(n=6).The limits of detection and quantification of As,Pb and Cd are 0.63,0.30,0.015 mg/kg and 2.1,1.0,0.05 mg/kg,respectively.
