Аnion exchanger

Anionite is a small granules (about 1 mm in diameter) from light yellow to dark yellow. This is a monofunctional ion-exchange resin with a gel and macroporous structure, a high-molecular polymer substance. Anion exchange resin - a copolymer of divinylbenzene and styrene, capable of entering into an anion exchange reaction in water and aqueous solutions. Contains one type of ionogenic groups - benzyltrimethylammonium.

According to the degree of dissociation, anion exchangers are divided into strongly electrolyte and weakly electrolyte, capable of exchanging their ions in a wide pH range. Strong base anion exchanger - for anions of strong and weak acids.

Weakly electrolyte ion exchangers are capable of exchanging their ions within narrow pH limits. Cation exchangers - in an alkaline medium, anion exchangers - in strongly acidic and only on anions of strong acids.

Obtained by chloromethylation of a copolymer of styrene with 8% divinylbenzene and subsequent amination with trimethylamine.

Chemical formula - C6H10O4

Where is it applied?

For water purification from weakly dissociating acids (carbonic, silicic) together with cation exchanger;

For deep water purification, chemical, pharmaceutical and food industries;

For waste and return water treatment;

In hydrometallurgy for softening and desalination of water;

In the chemical industry for the separation and purification of various substances.
