Anodic behavior of platinized titanium electrodes during the production of sodium hypochlorite solutions from natural waters

Data obtained radiometrically are presented which relate to the influence of current density, temperature, and salinity of the electrolyte on the anodic dissolution rate of platinum sheet and of the platinum coating of platinized titanium electrodes in natural waters of different composition. The influence of current interruptions on the wear of the platinum coatings is estimated. The anodic dissolution rates of two forms of platinum coatings are compared, viz., freshly deposited and after prolonged prior polarization
