Cationite is small granules (about 1 mm in diameter) from light yellow to dark brown.
It is a monofunctional strongly acidic ion exchange resin with a gel structure, high molecular weight polymer substance. Copolymer of styrene and divinylbenzene. It contains one type of fixed ions - sulfo groups attached to aromatic rings.
The main characteristic of cation exchangers is the presence of acidic groups in the composition, the hydrogen of which can be exchanged for metal ions present in solution. mechanical strength, osmotic stability and high chemical resistance to alkalis, acids, oxidants. Insoluble in water and organic solvents.
Non-melting, non-flammable, non-explosive, non-toxic, does not contain radioactive and ozone-containing substances. Resistant to high (110-120 ° C) temperatures. Its exchange capacity depends little on the pH of the medium. KU-2-8 cation exchanger is the most common cation exchanger used in the CIS. It is used in water treatment to soften and demineralize (demineralize) water.
Cation exchangers are often used in combination with anion exchangers to achieve a complex effect in water treatment. Cation exchanger is used in hydrometallurgy for the selective extraction of polyvalent metals, for the extraction of basic inorganic and organic substances from solutions, for the selective separation of valuable, biologically active substances from biological raw materials.
It is also used in the treatment of return and waste water, for the regeneration of electroplating and metalworking waste, for the separation and purification of various substances in the chemical industry and as a catalyst for organic synthesis. This is one of the most promising cation exchangers in solving problems of protecting water bodies from pollution.
