The combined effect of both concentration and pressure differences on electrical potential (Ad~) for two ion-exchanger membranes, one positively charged (AE) and another negatively charged (CE), measured with the membranes in contact with NaCI solutions was studied. Results show a linear dependence between Adp and pressure, independently if AC and AP have the same or opposite directions. The ra...

In article number 2006768, Hyukjin J. Kwon, Geunbae Lim, and Minsoo Lee introduce a multiscale-porous anion exchange membrane (MP-AEM), as an easily accessible anion-permselective material for the electrokinetic concentration of cationic species. The MP-AEM's highly streamlined fabrication process enables convenient cation-selective concentrator assembly, its demonstrated scalability shows grea...

Based on the home-made cation-exchange membrane (CEM) and bipolar membrane (BPM), electrodialysis with bipolar membrane (EDBPM) and electro-membrane reactor with three compartments (EMR-3) were developed to achieve in situ ion substitution and recovery of gluconic acid (GLH) from its sodium salt. Physicochemical and electrochemical properties of CEM and BPM were studied to assess their...
