Ion-exchange resin - Wikipedia
An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads , usually white or yellowish, fabricated from an organic polymer substrate.
What Is Ion Exchange Resin and How Does It Work?
Ion exchange is a reversible chemical reaction where dissolved ions are removed from solution and replaced with other ions of the same or similar electrical charge. Not a chemical reactant in and of itself, IX resin is instead a physical medium that facilitates ion exchange reactions.
Ion Exchange Resin - an overview | ScienceDirect Topics
An ion exchange resin is a network polymer with fixed ionic groups that can exchange counterions with the ionic components of a solution. These resins come in cation and anion forms, each with a specific number of mobile ionic sites determining their ion exchange capacity.
Understanding Ion Exchange Resins: - Ionic Systems
Ion exchange resins are small, highly porous beads typically made from an organic polymer substrate. These beads have a unique capability: they can exchange certain ions within a liquid without changing their own structure.
Ion-exchange resin | Synthetic Polymer, Adsorption Properties
In industrial and domestic applications, ion-exchange resins are used for the removal of calcium, magnesium, iron, and manganese salts from water (water softening), for purification of sugar, and for concentration of valuable elements, such as gold, silver, and uranium from mineral ores.
