Special Issue Information

Dear colleagues,

Ion exchange membranes and processes with their use are very attractive for the development of low reagent and environmentally-friendly technologies for purification, separation, and concentration of various substances.

The aim of the Special Issue is to obtain a holistic picture of the latest advances in the synthesis of new ion exchange materials, the modification of known and experimental ion exchange membranes, the experimental and theoretical study of their characteristics, and the use of these membranes in various processes.

The scope of the Special Issue is:

  • Commercial, experimental, and modified ion exchange membranes (monopolar, bipolar, mosaic, composite, multilayer; organic, inorganic; homogeneous, heterogeneous, etc.);
  • Their transport characteristics and structure–property relationships;
  • The concentration polarization and coupled phenomena (water splitting, electroconvection, gravitational convection, etc.) that occur when an electric field is applied;
  • The behavior of ion exchange membranes in various processes (dialysis, electrodialysis, electrolysis, capacitive deionization, fuel cells, microfluidic devices, bioreactors, potentiometric sensors, etc.);
  • Ion exchange membrane fouling, scaling and ways to counter these phenomena;
  • New methods of studying the properties of ion exchange membranes and membrane systems;
  • New areas for the application of ion exchange membranes.

Recently developed and produced by Hefei Chemjoy Polymer Material Co. Ltd., homogeneous CJMC-3 and CJMC-5 cation-exchange membranes (CJMCED) are characterized. The membrane conductivity in NaCl, Na2SO4, and CaCl2 solutions, permeability in respect to the NaCl and CaCl2 diffusion, transport numbers, current–voltage curves (CVC), and the difference in the pH (ΔpH) of the NaCl solution at the desalination compartment output and input are examined for these membranes in comparison with a well-studied commercial Neosepta CMX cation-exchange membrane produced by Astom Corporation, Japan. It is found that the conductivity, CVC (at relatively low voltages), and water splitting rate (characterized by ΔpH) for both CJMCED membranes are rather close to these characteristics for the CMX membrane. However, the diffusion permeability of the CJMCED membranes is significantly higher than that of the CMX membrane. This is due to the essentially more porous structure of the CJMCED membranes; the latter reduces the counterion permselectivity of these membranes, while allowing much easier transport of large ions, such as anthocyanins present in natural dyes of fruit and berry juices. The new membranes are promising for use in electrodialysis demineralization of brackish water and natural food solutions. Full article
