Layer-by-layer adsorption allows the creation of versatile functional coatings for ion exchange membranes, but the stability of the coating and resulting properties of modified membranes in their operation is a frequently asked question. This paper examines the changes in voltammetric curves of layer-by-layer coated cation exchange membranes and pH-metry of desalination chamber with a studied membrane and an auxiliary anion exchange membrane after short-term tests, including over-limiting current modes. The practical operation of the membranes did not affect the voltammetric curves, but enhanced the generation of H+ and OH− ions in a system with polyethylenimine modified membrane in Ca2+ containing solution. It is shown that a distinction between the voltammetric curves of the membranes modified and the different polyamines persists during the operation and that, in the case of polyethylenimine, there is an additional zone of growth of potential drop in voltammetric curves and stronger generation of H+ and OH− ions as indicated by pH-metry.

“…It should be noted that the concentrations of external solution were much lower than the ion exchange capacity of the substrate membrane (20 mM equivalent versus about 1.7 M equivalent per [ 37 ]), so an existence of relatively high Donnan potential difference [ 54 ] was expected.…”

One of the most important factors limiting the development of industrial processes is the consumption of large amounts of clean water and the generation of large amounts of wastewater. Pigments are available in a wide range of colors, consisting of small molecules practically insoluble in the medium and known to be unique compounds for many industries. They are widely used in dyestuff, cosmetics, food products, pharmaceuticals, manufacturing processes, etc. This study focuses on the removal of pigments and other components from wastewater discharged from pigment plants. The separation process was carried out in two stages: the first was to use prepared activated carbon as an adsorbent to separate the pigment, and then the separation process by electrodialysis to remove other components such as salts, acids, and others. This study considers prepared activated carbon (AC) as an effective separating adsorbent. The preparation process mainly included two-stage pyrolysis and activation using potassium hydroxide (KOH) and sodium hydroxide (NaOH).
