“…Pressure retarded osmosis (PRO), 20 reversible electrodialysis (RED), 21 capacitive mixing (CapMix), 22 mixing entropy batteries (MEB), 17 and neutralization batteries (NB) 23 are some of the relevant studied systems. The working principle of these technologies is to promote controlled mixing of diluted and concentrated solutions by means of solvent flow, as in case of PRO, or of solute flow, as in the case of RED, CapMix, MEB, and NB.…”

Ever-rising energy demand, fossil fuel dependence, and climate issues have harmful consequences to the society. Exploring clean and renewable energy to diversify the world energy matrix has become an urgent matter. Less explored or unexplored renewable energy sources like the salinity and proton gradient energy are an attractive alternative with great energy potential. This paper discusses important electrochemical systems for energy conversion from natural and artificial concentration gradients, namely capacitive mixing (CapMix), mixing entropy batteries (MEB), and neutralization batteries (NB); the working principle and thermodynamic formalism of these systems; and the materials employed in the assembly of these systems.

“…An important application of ion-exchange membranes is water treatment, which is commonly conducted by means of reverse osmosis or electrodialysis [34,35]. The first of these methods uses membranes that do not contain specific ion-exchange groups [36].…”

Membrane technologies using novel types of ion-exchange membranes comprising nanoparticles of inorganic substances-hybrid materials-have been vigorously developed in recent years. This modification leads to significant changes in the system of pores and channels and in the transport properties of the membranes. Owing to the changes, these materials exhibit considerable advantages over conventional membranes. This brief review analyzes the prospects for the use of hybrid ion-exchange membranes in water treatment systems, electrolysis cells, electrochemical current-generation devices, and sensors and in catalysis and gas separation processes.

“…The sodium lignin dissociates to Na + and lignin anion (lignin´), and the sodium salts of organic acids dissociate to Na + and organic acidic anions (A´) in solution. Selective blocking by the cationic exchange membrane prevented the organic acidic ions from penetrating the membrane, while the Na + can penetrate the membrane and transfer into the cathode chamber [21]. In the cathode chamber, the dissociated H + ions accept electrons and become hydrogen gas when they touched the cathode [22]; and the remaining -OH combines with the incoming Na + to form sodium hydroxide.…”

Black liquor is generated in Kraft pulping of wood or non-wood raw material in pulp mills, and regarded as a renewable resource. The objective of this paper was to develop an effective means to remove the water pollutants by recovery of both lignin and sodium hydroxide from black liquor, based on electrolysis. The treatment of a 1000 mL of black liquor (122 g/L solid contents) consumed 345.6 kJ of electric energy, and led to the generation of 30.7 g of sodium hydroxide, 0.82 g of hydrogen gas and 52.1 g of biomass solids. Therefore, the recovery ratios of elemental sodium and biomass solids are 80.4% and 76%, respectively. Treating black liquor by electrolysis is an environmentally friendly technology that can, in particular, be an alternative process in addressing the environmental issues of pulping waste liquor to the small-scale mills without black liquor recovery.
