In the electrochemical treatment of tissue with direct current the main reactions at the anode are the formation of oxygen in addition to acidification due to liberated hydrogen ions, and formation of chloride, if platinum is used as anode material. At the cathode hydrogen is formed and hydroxide ions are liberated. Calculations have been made for the two major anodic reactions. As a first approximation just one-dimensional diffusion is considered corresponding to the use of plate electrodes. It appears from these calculations that the liberated hydrogen ions determine the extension of the locally destroyed zone around the anode. The destructive effect of chlorine probably occurs in an inner zone close to the anode.
在采用直流电对组织进行电化学治疗时,若使用铂作为阳极材料,阳极的主要反应除了因氢离子释放导致酸化外,还会生成氧气,以及生成氯气。在阴极则会生成氢气并释放出氢氧根离子。已针对两个主要的阳极反应进行了计算。作为一阶近似,仅考虑对应平板电极使用情况的一维扩散。从这些计算结果可以看出,释放出的氢离子决定了阳极周围局部破坏区域的范围。氯气的破坏作用可能发生在靠近阳极的内部区域。
