DESCRIPTION

Product Description

Water Treatment Ion Exchange Resins are insoluble polymer beads containing functional groups that exchange ions with dissolved salts in water. These resins are classified as cation exchangers (strong/weak acid) and anion exchangers (strong/weak base), working individually or in mixed-bed systems to remove ionic contaminants through reversible chemical reactions.

Applications

Chemical Catalysis: Serves as an acid catalyst in organic synthesis reactions including esterification, hydrolysis, and alkylation.
Metal Ion Separation: Used in chromatographic separation of rare earth elements, amino acids, and metal ions.
Water Treatment: Employed in water softening, deionization, and demineralization processes.
Pharmaceutical Purification: Applied in purification of pharmaceuticals and biochemical compounds.
Analytical Chemistry: Used as a stationary phase for ion exchange chromatography in laboratory applications.
