“…Moreover, the amino acid transport depends on both the charged character and molecular size; however, the non-electrolyte was rejected and sucrose permeated under all experimental conditions. Higa et al [ 53 ] fabricated charged mosaic membranes from laminated structures of negatively/positively charged poly(vinyl alcohol) membranes. The authors found that the flux of salts and the permselectivity of membranes could be controlled by adjusting the charge density (numbers of ion pairs, a decrease in the domain size between the oppositely charged layers) and the cross-linking density (the annealing conditions).…”

“…In order to meet the requirement of large-scale preparation with low cost, the polymer blend and non-solvent induced phase separation method were adopted to fabricate charged mosaic membranes. Higa et al [ 53 ] prepared charged mosaic membranes from laminated structures of charged poly(vinyl alcohol) membranes, where the negatively charged base membranes and positively charged base membranes were alternately stacked. Compared with the Desalton ® membrane, there is a much higher permselectivity for salt of this membrane with a relatively lower flux.…”

Abstract:In the face of serious environmental pollution and water scarcity problems, the membrane separation technique, especially high efficiency, low energy consumption, and environmental friendly nanofiltration, has been quickly developed. Separation membranes with high permeability, good selectivity, and strong antifouling properties are critical for water treatment and green chemical processing. In recent years, researchers have paid more and more attention to the development of high performance nanofiltration membranes containing "ion pairs". In this review, the effects of "ion pairs" characteristics, such as the super-hydrophilicity, controllable charge character, and antifouling property, on nanofiltration performances are discussed. A systematic survey was carried out on the various approaches and multiple regulation factors in the fabrication of polyelectrolyte complex membranes, zwitterionic membranes, and charged mosaic membranes, respectively. The mass transport behavior and antifouling mechanism of the membranes with "ion pairs" are also discussed. Finally, we present a brief perspective on the future development of advanced nanofiltration membranes with "ion pairs".

“…An effective separation of the metal salts (electrolytes) and non-electrolytes is observed during the dialysis of their aqueous solutions through mosaic membranes (MM) [1] [2]. Mosaic membranes are most frequently synthesized as a set of parallel anion exchange areas (AEAs) and cation exchange areas (CEAs) [3]. Anions and cations are transported through the membrane by the parallel areas (anions are transported by the AEAs, and cations are transported by CEAs) without a violation of macroscopicelectro-neutrality [4] [5].…”

To separate salts of metals and non-electrolytes, the approach of dialysis through the composite membranes (CMs) is proposed. CM is a combination of cation and anion exchange areas. In the composite membrane, cations and anions are transferred through the respective exchange areas simultaneously without violation of macroscopic electro-neutrality. This provides a better transfer of salts than conventional ion exchange membranes (IEMs). The dialysis of the ethylene glycol aqueous salt solutions through the CMs was investigated. We have shown that the transport of salts through the composite membranes is more intensive (unlike IEM providing no transfer of salts from weakly mineralized aqueous solutions due to the Donnan exclusion) and the ethylene glycol transfer is not very significant, that is the basis of effective separation. The possibility to use of composite membranes for metal salt and other electrolyte separation is discussed.
