Abstract

The spectral composition of fluctuations of the concentration field in the stratified systems with ionexchange
membranes at intensive current regimes using Fourier-method was analyzed. The high noise
components of the concentration field in the solution at the boundary with anion-exchange МА-41M
membrane characterized by low catalytic activity to the heterolytic reaction of water dissociation and at the
boundary with cation-exchange МK-40/Nf membrane characterized by a high degree of surface
hydrophobicity were established
