Abstract

The paper presents a physicochemical model of the redox sorption of molecular oxygen from water by a metal-containing electron-ion exchanger. The model takes into account the dispersity of metal particles, the special features of their chemical oxidation, and interrelation between the total process rate and the properties of the ion-exchange matrix. This model was used to formulate the problem mathematically, obtain a numerical solution, and theoretically analyze it as depending on the main parameters of the sorption system. A criterion was introduced for estimating the contributions of the diffusion and kinetic stages taking into account the dispersity of metal particles.
