Enhanced desalination efficiency in modified membrane capacitive deionization by introducing ion-exchange polymers in carbon nanotubes electrodes

TiO2 nanorod-intercalated reduced graphene oxide as high performance electrode material for membrane capacitive deionization

“…Generally, charge efficiency is far from ideal value mainly caused by the co-ion expulsion from the electrode and weak adhesion between the porous electrode and substrate in addition to the blocking effect of the binder [50][51][52]. The charge efficiency (Λ) was obtained according to Eq.…”

Polymer coated Capacitive Deionization Electrode for Desalination: A mini review

“…Application of polyethyleneimine (cation exchange polymer) and dimethyl diallyl ammonium chloride (anion exchange polymer) into carbon nanotube-based electrode shows better improvement in desalination due to decreased coion effect. It also enhanced the contact adhesion between electrodes and ion exchange polymers compared to contact adhesion between electrodes and commercial ion exchange membranes [22].…”

Desalination and disinfection of inland brackish ground water in a capacitive deionization cell using nanoporous activated carbon cloth electrodes

“…New stand-alone desalting techniques like capacitive deionization (CDI) have addressed the issue by specifically operating in the brackish water salt regimes [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], which are predicted to be present even offshore beneath the continental shelf [21]. CDI involves the potential mediated separation of salt from water, rather than water from salt, as practiced in traditional desalting techniques like RO and MSF [22,23].…”
