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 - Wikipedia
Ion exchange resins are the physical medium that facilitates ion exchange reactions. The resin is composed of cross-linked organic polymers, typically polystyrene matrix and functional groups where the ion exchange process takes place.
Ion-exchange resin | Synthetic Polymer, Adsorption Properties
Ion-exchange resin, any of a wide variety of organic compounds synthetically polymerized and containing positively or negatively charged sites that can attract an ion of opposite charge from a surrounding solution. The resins commonly consist of a …
Ion Exchange Resins: Definition & Applications - Excedr
2022年7月26日 · Ion Exchange resins are an efficient approach to replacing acids, alkalis, and metal ion catalysts in a range of chemical reactions, including inversions, hydrolysis, hydration, and polymerization reactions.
Ion Exchange (IX) - DuPont
Ion exchange resins remove harmful contaminants from liquids, replacing them with beneficial, desired ions. Ion exchange is used in water treatment, including water softening, industrial demineralization, condensate polishing, ultrapure water production, and wastewater treatment.
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.
Ion Exchange & Water Demineralization Handbook | Veolia
Ion exchange systems are used for efficient removal of dissolved ions from water. Ion exchangers exchange one ion for another, hold it temporarily, and then release it to a regenerant solution. In an ion exchange system, undesirable ions in the water supply are …
Ion Exchange In Water Treatment - Atlas Scientific
2022年10月31日 · Ion exchange in water treatment involves removing undesirable ionic contaminants from the water by exchanging them with another ionic substance. The four methods of ion exchange are water softening, deionization, demineralization, and dealkalization. It is essential to remove contaminants in water to make it safe.
Ion exchange is the reversible interchange of ions between a solid (ion exchange material) and a liquid in which there is no permanent change in the structure of the solid. Ion exchange is used in water treatment and also provides a method of separation in many non-water processes.
