  • 摘要: 采用丝网印刷电极，通过电化学沉积法修饰纳米金颗粒，对化妆品中重金属Hg2+进行快速测定.实验结果表明，Hg2+在金纳米粒子修饰电极上可得到灵敏的溶出峰，在优化的实验条件下Hg2+在5-160 μg·L-1范围内呈现良好的线性关系，相关系数为0.992，检测限为0.3 μg·L-1.该方法简便、快速、灵敏度较高、具有较好的选择性和准确性，能满足化妆品中Hg2+含量的检测分析.
    Abstract: We used gold nanoparticle-modified screen-printed carbon electrodes (AuNPs-SPCE) to detect Hg2+ in cosmetic by square wave anodic stripping voltammetry (SWASV). The experimental results show that a sensitive stripping peak of Hg2+ was obtained.Under the optimal conditions, the linear range was 5-160 μg·L-1with the r value of 0.992 and the limit of detection was 0.3 μg·L-1(n=20). This method was simple,fast,sensitivity,selectivity and accurate, and was used to detect trace Hg2+ in cosmetic with satisfactory results.
