Abstract—The behavior of an immobile granular sorbent bed in one-component sorption in a column reactor
is described in terms of the kinetic model of redox sorption taking into consideration the dispersity of metal
particles, their radial distribution, peculiarities of chemical oxidation, and the relation of the overall rate of the
process to the properties of the ion exchange matrix. The mathematical problem is formulated and solved
numerically; the solution is analyzed theoretically in relation to the basic parameters of the sorption system. A
satisfactory agreement is obtained between the experimental and calculated data on the reductive sorption of
molecular oxygen from water on a copper-containing electron-ion exchanger.
