Kationit it is synthetic organic ion-exchange pitch capable to exchange cations. Most often it is copolymer of styrene and divinyl benzene.
Kationit presents itself insoluble particles in the form of granules, about 1 mm in the diameter.
Color of a kationit can be from light yellow to dark brown.
Ability at kationit of reaction of an ionic exchange occurs at the expense of special functional groups.
Characteristics of kationit:
Main harakteristka of chemical and physical properties of kationit following: particle size distribution, mechanical durability, chemical and thermal firmness, osmotic stability, extent of swelling, ion-exchange capacity dynamic, static and working, bulk weight, etc.
Structure of a kationit:
Forms of a kationit:
Kationit happens in various cationic forms. generally it is Sodium form (Na-form) and the Hydrogen form (N-form).
Depending on a form kationit changes the ions deleted from water or for sodium an ion or for the N-ion. Kationita in Sodium to a form are most often used for softening of water for domestic and commercial needs. Kationita in the N-form are used for an obessolivaniye of water and special water treatment.
Below in drawing the example of work of a kationit in sodium to a form is given.
The principle of action of kationit in sodium to a form:
Application of kationit:
- softening and obessolivany waters in systems of water treatment
- for cleaning reverse and sewage
- for division and release of non-ferrous and rare metals in hydrometallurgy
- for regeneration of waste in galvanic and metalworking productions
- in chemical industry
in organic synthesis in the form of the catalyst
