Capacitive deionization (CDI) has received much attention, which is considered as a promising electrochemical water desalination technology. However, an obstacle to its conventional application the limited ion removal capacity of carbon electrodes induced by electrical double layer. Here, novel CDI system, called multichannel redox (MC-RCDI), was proposed enhance performance utilizing couple ferricyanide/ferrocyanide well adsorption electrodes. In MC-RCDI, feed in middle channel fully...
Robust, energy-efficient separation technologies for desalination and the removal of organic contaminants are critical in addressing growing concerns about water shortage pollution. Here, we propose a generalized strategy advancing electrodialysis using redox-flow concepts, by implementing water-soluble redox-copolymer, poly(ferrocenylpropylmethacrylamide-co-[2-(methacryloyloxy)ethyl]trimethylammonium chloride), P(FPMAm-co-METAC), to eliminate need anion-exchange membranes (AEMs) deploy...
Rapid growth of the industrial and electronics sectors has led to an ever-mounting demand for gold. Gold mining can be highly resource-intensive, due need selective gold separations from dilute streams, in presence multicomponent metallic species.

Abstract The design of molecularly selective membranes is paramount importance in the electrochemical separation organic acids from complex fermentation streams, due to presence multicomponent species. However, current membrane‐integrated technologies have relied on ion‐exchange that lack intrinsic ion‐selectivity, thus preventing their application for value‐added recovery competing ions.
