一、电极的选择 固体电极伏安法的实际应用与日俱增,国外多用于溶出伏安法(阳极溶出或阴极溶出),而国内许多生产单位则对固体电极正向伏安法感兴趣,因它在一定条件下可代替滴汞电极的经典极谱分析,减少用汞量及对环境的污染。因此,极谱分析工作者研究了各种固体电极,按其性质大致可分为:涂汞电极—各种涂汞及汞膜电极,非汞电极—石 First, the choice of electrode The solid electrode voltammetry practical application of growing, more for foreign use of stripping voltammetry (anodic dissolution or cathodic dissolution), while many domestic production units are on the solid electrode positive voltammetry interest because it is Under certain conditions, it can replace the classical polarographic analysis of drop mercury electrodes, reduce the amount of mercury and the pollution of the environment. Therefore, polarographic workers have studied a variety of solid electrodes, which can be broadly classified into the following categories according to their properties: coated mercury electrodes - various coated mercury and mercury film electrodes, non-mercury electrode-stone
