Abstract

The dynamics of molecular oxygen redox-sorption from water by granular layer nanocomposites
metal (Ag, Cu) - sulfo cation exchanger KU-23 cathodic galvanostatic polarization oxygen limiting diffusion
current mode is studied. The possibility of a stationary process is shown. Oxygen concentration in water at
the outlet of the granular bed of silver nanocomposite is close to the theoretically calculated by external
diffusion model, and for copper-containing nanocomposite oxygen concentration is lower due to the chemical
activity of copper nanoparticles.
