Cation exchange membranes are used for electrochemical reduction of CO 2 in alkaline media, where the anion conductivity hydroxide (OH − ) and bicarbonate (HCO 3 essential process. Any partial anionic species containing (i.e. or carbonate (CO 2− ions) causes parasitic transport , a critical issue technology. In this work, cation contacted with support electrolytes is experimentally studied hydr...

In ion-exchange membranes (IEMs), the concentration-induced tradeoff between conductivity and permselectivity constrains process performance. This study investigates impacts of different electrolytes on conductivity-permselectivity commercial cation anion exchange membranes. Nine electrolyte solutions containing mono-, di-, trivalent ions, spanning 1.5 orders magnitude in concentration were exa...

The use of commercially available cation and anion exchange membranes to generate power from industrial wastewater obtained from three different industries (food, alcohol and dairy factories) without the addition of external microorganisms or chemicals by using microbial fuel cells (MFCs) was investigated. The results indicate that the original mixed culture of microorganisms presented in waste...

Novel self-crosslinked alkaline anion exchange membranes with high alkaline stability, excellent dimensional stability and extraordinary methanol resistance were synthesized successfully without using any catalyst or a separate crosslinker.

Poly(hexafluoropropylene-co-tetrafluoroethylene) (FEP) was successfully radiationgrafted with vinylbenzyl chloride (VBC). Subsequently amination with trimethylamine followed by ion exchange with aqueous hydroxide yielded alkaline anion-exchange membranes (AAEMs). Experimental parameters were established for maximising the degree of grafting (d.o.g.); the optimum treatment duration for maximum a...
