实验证明:一定条件下。玻碳汞膜电极作为工作电极,有适量CTAB的存在,用D.P.A.S.V法测痕量金属镉的增敏效果可达10倍以上。此法已成功应用于测定食品中的痕量镉。
Experiments show that: under certain conditions. Glassy carbon mercury electrode as a working electrode, there is the amount of CTAB presence, with D.P.A.S.V method to detect traces of metal cadmium sensitization effect of up to 10 times. This method has been successfully applied to the determination of trace amounts of cadmium in food.
