Ion-exchange membranes are transport melted ions across a conductive polymeric membrane. The membranes are frequently used in chemical recovery applications and desalination, moving ions from one solution to another with little channel of water. These are made of a polymeric material attached to charged ion clutches. Anion-exchange membranes contain fixed cationic groups with predominantly mobile anions. The most famous electrically driven Ion Exchange process is electrodialysis. Electrodialysis which is also referred to as electrodeionisation.
