The interplay between the ion exchange capacity, water content and concentration dependences of conductivity, diffusion permeability, counterion transport numbers (counterion permselectivity) CJMA-3, CJMA-6 CJMA-7 (Hefei Chemjoy Polymer Materials Co. Ltd., China) anion-exchange membranes (AEMs) is analyzed using application microheterogeneous model to experimental data. structure-properties relationship for these examined when they are bathed by NaCl Na
The broad possibilities of electrochemical impedance spectroscopy for assessing the capacitance interphase boundaries; resistance and thickness foulant layer were shown by example AMX-Sb membrane contacted with red wine from one side 0.02 M sodium chloride solution other side. This enabled us to determine what extent foulants affect electrical ion-exchange membranes, ohmic diffusion layers, intensity water splitting, electroconvection in under- over-limiting current modes. It was established...
Anion-exchange membranes modified with a polyquaternium-22 (PQ-22) polymer were studied for their use in electrodialysis. The of PQ-22 modification makes it possible to “replace” weakly basic amino groups on the membrane surface quaternary groups. It was found that content is higher than carboxyl groups, which reason effectiveness this even when modifying Ralex AHM-PES initially contain only In case containing efficiency higher. charge MA-41P increased, while limiting current density...
The paper shows the possibility of using a microheterogeneous model to estimate transport numbers counterions through ion-exchange membranes. It is possible calculate open-circuit potential and power density reverse electrodialyzer data obtained. Eight samples heterogeneous membranes were studied, two for each following types membranes: Ralex CM, AMH, MK-40, MA-41. Samples in pair differed year production storage conditions. In work, these named “batch 1” 2”. According model, counterions, it...
Abstract The deposition of several alternating anion- and cation-exchange surface layers (layer-by-layer method) is a promising technique for the modification ion-exchange membranes, which makes it possible to essentially increase their selectivity singly charged ions. This paper presents one-dimensional model, based on Nernst–Planck–Poisson equations describes competitive transfer doubly ions through multilayer composite membrane. It has been revealed first time that, as in earlier studied...
