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. Browse by Product Type. Browse by Brand. Featured Products.

Gunaji New Mexico State University Las Cruces, New Mexico Cooperative Agreement CR Project Officer Steven W. Hathaway/Richard P. Lauch Drinking Water Research Division Water . An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion is an insoluble matrix (or support structure) normally in the form of small (– mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate. The beads are typically porous, providing a large surface area on and inside them.
Analytical Chemistry, Volume Ion Exchange in Analytical Chemistry provides a broad survey of the important role that ion exchange can and should play in chemical analysis. This book focuses on the plate-equilibrium theory of chromatography, which is less difficult theoretically than the mass-transfer Edition: 1. Ion exchange has been widely applied in technology of chemical separation of noble metal ions. This is associated with dissemination of methods using various ion exchange resins which are indispensable in many fields of chemical industry. Due to small amounts of noble elements in nature and constant impoverishment of their natural raw materials, of particular importance are Cited by: 2.

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. Comprehensive text provides sound understanding of the relevant factors in ion exchange and the theoretical tools needed to solve specific problems.

Not a chemical reactant in and of itself, IX resin is instead a physical medium that facilitates ion exchange reactions.
The resin itself is composed of organic polymers that form a. DOWEX MARATHON A Type 1 Strong Base Anion Exchange Resin General Information DOWEX* MARATHON* A resin is a high capacity, gel type 1, strong base anion exchange resin of uni-form bead size distribution.
It is a based on a styrene-divinyl benzene copolymer matrix with quaternary ammonium functional groups. DOWEX MARATHON A resin isFile Size: KB. The ion-exchange process is a stoichiometric and reversible process wherein an ion from the solution is replaced with a similarly charged ion attached to an immobile solid phase (e.g., ion-exchange device) in order to fulfill the electroneutrality requirement.
