ION EXCHANGE PROCESS: An ion-exchange resin is a polymer or resin that's activated as a medium for Ion exchange. It is an insoluble matrix (or support structure) normally in the form of small (0.5–1 mm diameter) microbeads, usually white or yellowish, fabricated from an organic polymer substrate. This is typically porous, providing a large surface area on and inside them. The trapping of ions occurs along with the accompanying release of other ions, & thus the process is called Ion exchange.
