Transport Properties and Structure of Anisotropic Composites Based on Cation-Exchange Membranes and Polyaniline
Comprehensive characterization of basic MK-40 and Ralex CMH heterogeneous cation-exchange membranes and composite membranes with polyaniline based on them is performed including the determination of specific electrical conductivity and diffusion permeability; measurement of current–voltage curves in solutions of sodium, calcium, and magnesium chlorides and hydrochloric acid and curves of distribution of water with respect to the bond energies and effective pore radii as well as assessment of the transport structural parameters of a microheterogeneous model. The time of synthesis of polyaniline on the surface of cation-exchange membranes for obtaining samples with an anisotropic structure and asymmetric electric transport properties is determined by successive diffusion of a solution of an oxidizing agent and a monomer through the membrane into water. It is shown based on the analysis of the electric transport properties, structural characteristics, and model transport structural parameters of the membranes in solutions of singly and doubly charged ions that the obtained materials are promising for use in the processes of electrodialysis desalination of multicomponent solutions.
期刊介绍：
The journal Membranes and Membrane Technologies publishes original research articles and reviews devoted to scientific research and technological advancements in the field of membranes and membrane technologies, including the following main topics:novel membrane materials and creation of highly efficient polymeric and inorganic membranes;hybrid membranes, nanocomposites, and nanostructured membranes;aqueous and nonaqueous filtration processes (micro-, ultra-, and nanofiltration; reverse osmosis);gas separation;electromembrane processes and fuel cells;membrane pervaporation and membrane distillation;membrane catalysis and membrane reactors;water desalination and wastewater treatment;hybrid membrane processes;membrane sensors;membrane extraction and membrane emulsification;mathematical simulation of porous structures and membrane separation processes;membrane characterization;membrane technologies in industry (energy, mineral extraction, pharmaceutics and medicine, chemistry and petroleum chemistry, food industry, and others);membranes and protection of environment (“green chemistry”).The journal has been published in Russian already for several years, English translations of the content used to be integrated in the journal Petroleum Chemistry. This journal is a split off with additional topics.
