Explanation

Also known as organic ion exchange resin, organic ion exchanger. It refers to the general name of various cation exchange resin, anion exchange resin and characteristic ion exchange resin, which are made of organic polymers as the skeleton materials and are introduced into active exchange groups through sulfonation, chloromethylation, amination, hydrolysis and other chemical reactions, as well as corresponding post-treatment. Organic polymers include styrene divinylbenzene copolymer, methyl methacrylate divinylbenzene copolymer, phenol formaldehyde condensation polymer, polysulfone, polyphenylene oxide, tetrafluoroethylene perfluoroether copolymer, polyvinyl chloride containing styrene divinylbenzene impregnated monomer and then polymerization. In structure, it usually consists of three parts: irregular macromolecule skeleton composed of hydrocarbon chains with three-dimensional spatial network structure; Functional groups connected to the skeleton; Anti ions with opposite charges to functional groups. The exchange reaction between ion exchange resin and isotropic ions in water is usually reversible chemisorption. It is mainly used for bating of water quality, preparation of high-purity water and removal of ionic pollutants in water.
