KU-2-8 cation exchanger (ion exchange resin) represents small granules (about 1 mm in the diameter) from light yellow till dark brown color. It is monofunctional highly acid ion exchange resin with gel structure, high-molecular polymer substance. Styrene copolymer and divinyl benzene. Contains one type of the fixed ions - the sulfonate groups attached to aromatic rings. The main characteristic of cation exchangers is presence at structure of acid groups which hydrogen can exchange on ions of the metals which are available in solution.
Differs in mechanical strength, osmotic stability and high chemical resistance to influence of alkalis, acids, oxidizers. It is water-insoluble also organic solvents. Not fusible, nonflammable, inexplosive, nontoxic, does not contain radioactive and ozonosoderzhashchy materials. It is steady against action high (110-120 °C) temperatures. Its exchange capacity depends from rn Wednesdays a little.

Use of KU-2-8 cation exchanger.
KU-2-8 cation exchanger is the most widespread cation exchanger applied in the CIS. It is applied at water treatment to softening and demineralization (desalting) of water. Often cation exchanger is applied in combination with anion exchangers, to achievement of complex effect in water treatment. Cation exchanger akhodit application in hydrometallurgy for selective elution of polyvalent metals, for extraction from solutions of non-organic and organic substances of the main character, for the selection release of valuable, biologically active agents from bioraw materials.
Also it is applied when cleaning returnable and drain waters, to regeneration of waste of galvanotechnics and metal working, to division and purification of different substances in chemical industry and as the catalyst for organic synthesis.
It is one of the most perspective cation exchangers in problem solving of protection of reservoirs from pollution.
