ELECTROCHEMICAL STABILITY OF STRONG BASIC ANION EXCHANGE MEMBRANES IN CONDITIONS OF HIGH INTENSIVE ELECTRODIALYSIS PROCESS

abstract 1041410045 issue 104 pp. 617 – 629 30.12.2014 ru 1648
The stability of strongly basic anion-exchange membranes MA-41-2P (JSC "Schekino-Nitrogen", Russia) and AMX (Tokuyama Soda, Japan) under intensive current regimes was investigated in the current study. The process of water molecules dissociation at current densities above the limiting one in 0.01 M sodium chloride solution was studied in detail. The length of the electroconvective instability at the membrane / solution interface at currents exceeding the limiting current was measured by laser interferometry

INVESTIGATION OF TRANSPORT OF SALT IONS IN THE EXPERIMENTAL ELECTROCHEMICAL CELL WITH ROTATING DISK MEMBRANE

abstract 0941310025 issue 94 pp. 335 – 346 27.12.2013 ru 1255
This work is a continuation of [1], which was devoted to the investigation of the hydrodynamics of the experimental electrochemical cell with rotating disk cation exchange membrane. This article focuses on the transport of salt ions in a closed cell at different initial experimentation with modes of exact current regimes. The main regularities of transport of salt ions and membrane equal accessible surface were set

MATHEMATICAL MODELING AND NUMERICAL STUDY OF THE HYDRODYNAMICS OF THE EXPERIMENTAL ELECTROCHEMICAL CELL WITH ROTATING DISK MEMBRANE

abstract 0941310024 issue 94 pp. 324 – 334 27.12.2013 ru 1294
This article investigates hydrodynamic of experimental electrochemical cell with rotating disk in the cation exchange membrane. We have also investigated the flow in open, with the free surface of the solution and in hermetically closed cells. The main regularities of the hydrodynamics of the experimental cell at its real size were set

VOLTAMMETRY AND ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY OF MEMBRANE SYSTEMS UNDER STABILIZED DIFFUSION LAYER THICKNESS

abstract 1131509094 issue 113 pp. 1326 – 1342 30.11.2015 ru 1181
The current-voltage characteristics and the number of effective ion transfer, as well as the frequency spectrum of the electrochemical impedance of multilayer ion-exchange membranes in a stable and controllable thickness of the diffusion layer were measured, using the of rotating membrane disk complex. The article presents a comparative analysis of the frequency spectra of the electrochemical impedance of the source and a surface-modified monopolar anion exchange membranes in 0.01 M sodium chloride was made. The process of water molecules dissociation at current densities above the limiting one in 0.01 M sodium chloride solution was studied in detail
