为研究烟草中金属镉对人体健康的危害,采用玻碳汞膜电极阳极溶出伏安法对烟草中的金属镉进行了测定。实验确定了最佳分析条件,该方法的最低检测限为2PPb,回收率为90—105％,所测香烟中含镉量为0.07—0.40微克/支。
In order to study the hazard of metal cadmium in tobacco on human health, the determination of metal cadmium in tobacco by anodic stripping voltammetry using glassy carbon mercury electrode was carried out. The optimal analytical conditions were determined experimentally, with the lowest limit of detection (LOD) of 2 PPb and the recovery of 90-105%. The content of cadmium in cigarettes measured was 0.07-0.40 μg / branch.
