Abstract
The paper presents the results of the numerical simulation performed in a unidimensional formulation for a cell containing an ion-selective region. The employed mathematical model takes into account the nonideal selectivity of the ion-exchange region and the presence of a convective electrolyte solution flow through it. The flow has been found to influence the selectivity of the ion-exchange region. The electric current through the system may be both enhanced and diminished depending on a realized current regime, namely, underlimiting or limiting. The understanding of this effect will be useful for practical applications, such as analyte preconcentration systems in microlaboratories for chemical analysis of biological liquids and electrobaromembrane separation systems.
期刊介绍:
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
