荧光光电化学法测定护肤品铅、汞等6种重金属含量

Fluorescence photoelectrochemical method for determining the content of six heavy metals,including lead and mercury,in skincare products

建立荧光光电化学分析法,同时测定护肤品中的As、Pb、Cr、Ag、Cd、Hg。样品经过消融,采用光电化学技术进行检测,6种重金属含量在线性范围内呈现良好的线性关系,相关系数达到0.999968,加标回收率为99.38%~104.86%,相对标准偏差(RSD)为0.055%~1.10%,方法的检出限在0.0035~0.007ug/mL。本方法对于护肤品多种重金属含量的检测分析结果准确率高,可靠性强,适合检测护肤品中的多种重金属含量的检测。

A fluorescence photoelectrochemical analysis method was established to simultaneously determine As,Pb,Cr,Ag,Cd,and Hg in skincare products.The samples were ablated and detected using photoelectrochemical technology.The content of six heavy metals showed a good linear relationship within the linear range,with a correlation coefficient of 0.999968.The recovery rate for spiking was 99.38%~104.86%,and the relative standard deviation(RSD)was 0.055%~1.10%.The detection limit of the method was 0.0035~0.007ug/mL.This method has high accuracy and strong reliability in detecting and analyzing the content of various heavy metals in skincare products,making it suitable for detecting the content of various heavy metals in skincare products.
