The nature of two transition times on chronopotentiograms of heterogeneous ion exchange membranes: 2D modelling

Autor: Victor Nikonenko, Vladlen S. Nichka, Andrey V. Nebavskiy, Mahamet K. Urtenov, S.A. Mareev

Publikováno v: Journal of Membrane Science. 575:179-190

Chronopotentiometry is largely used for electrochemical characterization of ion-exchange membranes. Nevertheless, the theory is poorly developed in the range of overlimiting currents. This paper proposes a two dimensional convective-diffusion model o

Mathematical Modeling of the Effect of Water Splitting on Ion Transfer in the Depleted Diffusion Layer Near an Ion-Exchange Membrane

Water splitting (WS) and electroconvection (EC) are the main phenomena affecting ion transfer through ion-exchange membranes in intensive current regimes of electrodialysis. While EC enhances ion transport, WS, in most cases, is an undesirable effect

Modelling of Ion Transport in Electromembrane Systems: Impacts of Membrane Bulk and Surface Heterogeneity

Autor: A. V. Kovalenko, Victor Nikonenko, Gérald Pourcelly, Mahamet K. Urtenov, S.A. Mareev, Andrey Nebavsky

Publikováno v: Applied Sciences, Vol 9, Iss 1, p 25 (2018)

Artificial charged membranes, similar to the biological membranes, are self-assembled nanostructured materials constructed from macromolecules. The mutual interactions of parts of macromolecules leads to phase separation and appearance of microhetero

Effect of electroconvection during pulsed electric field electrodialysis. Numerical experiments

Autor: A. V. Kovalenko, A.M. Uzdenova, Victor Nikonenko, Mahamet K. Urtenov

Publikováno v: Electrochemistry Communications, Vol 51, Iss, Pp 1-5 (2015)

One of the ways of improving electrodialysis (ED) and some microfluidic processes is the optimization of current regime. It is recognised now that the use of pulsed electric fields (PEF) in ED allows enhancement of mass transfer and mitigation of fou

Desalination at overlimiting currents: State-of-the-art and perspectives

Autor: Gérald Pourcelly, Mahamet K. Urtenov, Victor Nikonenko, Natalia Pismenskaya, Philippe Sistat, Jongyoon Han, A. V. Kovalenko

Desalination, Elsevier, 2014, 342, pp.85-106. ⟨10.1016/j.desal.2014.01.008⟩

For about 60 years, it is known that “limiting current” density does not really limit the current density in electrodialysis (ED). The use of intensive currents allows one to decrease the area of expensive ion-exchange membranes, hence to obtain

Decoupling of the Nernst−Planck and Poisson Equations. Application to a Membrane System at Overlimiting Currents

Autor: Victor Nikonenko, Natalia M. Seidova, Mahamet K. Urtenov, Evgeniya V. Kirillova

Publikováno v: The Journal of Physical Chemistry B. 111:14208-14222

This paper deals with one-dimensional stationary Nernst-Planck and Poisson (NPP) equations describing ion electrodiffusion in multicomponent solution/electrode or ion-conductive membrane systems. A general method for resolving ordinary and singularly

Publikováno v: Separation and purification technology, 1998(14), 255-267. Elsevier

The long-term goals of this work is to develop a better understanding of the coupled transport phenomena role in enhancement of salt ions transfer at electrodialysis of moderate-dilute and dilute electrolyte solutions in membrane modules of various c
