“…Zehra et al also fabricated composite CEM by using various mass compositions of PVC and tin aluminium molybdophosphate (TAMP) [32]. Four combinations with different mass ratios of binder (PVC) and exchanger (TAMP) were tested and the ratio of 1:3 (polymer to inorganic filler) was found to be most reliable formation for obtaining fine ion transport properties (e.g.…”

Blue energy can be harvested from salinity gradients between saline water and freshwater by reverse electrodialysis (RED). RED as a conversion technique to generate blue energy has received increasing attention in recent decades. As part of the RED system, ion exchange membranes (IEMs) are key elements to the success of future blue energy generation. However, its suboptimal performance often limits the applications and stagnates the development of the technology. The key properties of IEMs include ion exchange capacity, permselectivity, and electrical resistance. The enhancement of such physical and electrochemical properties is crucial for studying energy production with acceptable output efficiency on a commercial scale. Recently, many studies have tried blending nanotechnology into the membrane fabrication process. Hybridizing inorganic nanomaterials with an organic polymeric material showed the great potential of improving electrical conductivity and permselectivity, as well as other membrane characteristics for power performance. In this short review, recent developments on the IEM synthesis in association with potential nanomaterials are reviewed and raising issues regarding the application and commercialization of RED-based energy production are discussed.

“…The bi-ionic potential (BIP) is defined as a potential difference arising between the solutions of different electrolyte with same molar concentrations at a constant temperature and pressure when they are separated by a uniform charged membrane [13][14][15]. Depending on the transport mechanism or the assumption made in the derivation, the permeability ratio has been given various physical meaning as mobility ratio [16], ion exchange equilibrium constant [17], the product of the mobility ratio and Donnan ratio [18,19], the product of the mobility ratio and the distribution coefficient ratio [20], the product of the mobility ratio and ion exchange equilibrium constant [21,22] or the product of the equivalent conductance ratio and the ratio of partition coefficient [23]. Sandblom and Eisenman [23][24][25] have discussed the significance and implication of the observed permeability ratio.…”

Parchment impregnated Ba(II) molybdate artificial membrane was prepared by the ion-interaction method using BaCl2 and Na2MoO4 solutions. The prepared membrane was characterized by sophisticated instrumental techniques such as Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Fourier-transform infrared (FT-IR) spectroscopy, Thermogravimetric analysis (TGA)/Differential thermal analysis (DTA), X-ray diffraction (XRD) and Energy dispersive X-ray (EDX) analysis. The artificial membrane was tested for its antimicrobial activity against Gram-negative (Escherichia coli and Pseudomonas aeruginosa) and Gram-positive (Staphylococcus aureus) microorganism. The effective fixed charge density of the prepared membrane has been used individually to calculate theoretical bi-ionic potentials (BIP) and compared with experimentally determined values of bi-ionic potential. The selectivity of ions for the membrane has been found as K+>Na+>Li+ which on the basis of the Eisenman-Sherry model of membrane selectivity, points towards the low field strength of the charge groups joined to the membrane matrix. Membrane conductance values has also been experimentally determined.Â Â
