Macrokinetics and dynamics of the oxygen redox-sorption by metal-ion exchanger nanocomposites when electrochemical polarization

Abstract

A mathematical description of the oxygen redox-sorption macrokinetics and dynamics by metal-ion
exchanger nanocomposites was given with current component introduction to know problem solution of the
metal nanoparticles oxidation. The oxygen external diffusion (current component), internal stages diffusion
and reaction (without current components) were separated in space and time. It was given a numerical
analysis of dynamic curves of the water electrochemical deoxygenation. Numerical and experimental dates
were correlated. Conditions of process exit to stationary regime was founded.
