摘　　要：用原子吸收分光光度法(AAS)测定洗发水、护发素、染发剂三类洗护发产品中重金属元素Pb,Cr,Cd,Ni,Cu,Zn,Co和Fe的含量。结果表明:8种重金属元素的检出限范围均低于1.00 mg/kg,符合我国化妆品卫生标准中限定的重金属含量的要求,8种重金属元素的回收率均在96.30%~108.30%之间,相对标准偏差均在1.00%以下(n=6),相关系数均大于0.9990,该方法的线性相关良好,所测结果准确度能满足分析要求。同时,根据产品的种类及作用进行了对比分析可知,为满足产品需求,Zn,Fe和Pb等重金属元素在洗护发产品中均有检出且含量较高。The contents of heavy metal elements Pb,Cr,Cd,Ni,Cu,Zn,Co and Fe in shampoo,conditioner and hair dye were determined by atomic absorption spectrophotometry(AAS).The results showed that the detection limits of eight heavy metal elements are all lower than 1.00 mg/kg,which meets the requirements of the limit of heavy metal content in the hygienic standard of cosmetics in China.The recoveries of eight heavy metal elements are all between 96.30%and 108.30%,the relative standard deviation is less than 1.00%(n=6),and the correlation coefficient is greater than 0.9990.The linear correlation of the method is good,and the accuracy of the measured results can meet the analysis requirements.Additionally,the study conducted a comparative analysis based on the types and functions of the products.It could be seen that in order to meet the demand of product,Zn,Fe,Pb and other heavy metal elements were detected in hair care products and the contents are high.
