Description
KU-2-8 ion exchange resin — GOST 20298-74. Is monofunctional highly acid cation exchanger of polimeralizatsionny type. Differs in good osmotic stability, high chemical resistance to influence of alkalis, acids, oxidizers; it is water-insoluble also organic solvents.
KU-2-8 cation exchanger not fusible, nonflammable, inexplosive, nontoxic, does not contain radioactive and ozonosoderzhashchy materials. Is issued in the form of grains from light yellow till dark brown color. Cation exchanger is characterized by set of chemical and physical properties. Main physical properties of cation exchanger: particle size distribution (grain size), mechanical strength, osmotic stability, structure of cation exchanger, swelling value in solutions and bulk weight. Main chemical properties: chemical resistance, acidity, exchange capacity, specific consumption of reagents and washout water with the set removal depth from water of ions, thermal endurance. Ranges of application: water treatment, gidrometalllurgiya, galvanotechnics, sewage treatment.

Ion exchange resins — synthetic high-molecular organic ionites which divide on cation-exchange, anion-exchange and amphoteric (or bipolar).
Cation exchange resins happen both strong, and subacid, and anion-exchange — strong and weak-basic. Ion exchange resins can be considered, in principle, as insoluble polyelectrolytes. Polyvalent, i.e. multiply charged, the ion forming structural framework of ion exchange resin is practically not mobile because of the huge molecular weight. This ion framework connects small mobile ions of opposite sign which are capable to equivalent exchange for ions of surrounding solution.
Receive ion exchange resins polymerization, polycondensation or by polymeranalogous reactions (i.e. the called chemical treatment of the polymer which was not possessing before properties of ionite). Among commercial-grade ion exchange resins pitches on the basis of styrene copolymers and divinyl benzene were widely adopted. Among them highly acid cation exchangers (for example, KU-2-8), strong and weak-basic anion exchangers (for example, AB-17-8). The directed synthesis of ion exchange resins allows to create materials with the set running characteristics.

Ion exchange resins use for desalting of water, extraction and division of rare elements, cleaning of products of organic and inorganic synthesis.

Ion exchange resin has found broad application in the field of purification of drinking and trade effluent. Unique property of ion exchange resin - to react with the ions which are contained in aqueous solution and to change its structure.

In systems of water treatment ion exchange resin is used for release of metals from water, mitigation and removal of salts. Besides, ion exchange resin is used for purification of secondary waters in systems of the sewerage, the water used when processing metals, and also different substances in chemical industry.

Ion exchange resins are subdivided into cation exchangers (for example, KU-2-8 cation exchanger) or anion exchangers. The first absorb positively charged particles, the second - negatively charged. From here also scope of these or those ion exchange resins flows: cation exchangers, in combination to weak-basic anion exchangers use for water desalting, and strong-basic anion exchangers - for water after-treatment.
Receiving such chemical compound as ion exchange resin became huge find as for those who are engaged in purification of trade effluents, and for those who purify water in living conditions. However quality of that ion exchange resin which is used when cleaning is important.

On the website of the Trade Federation company you will find the most qualitative ion exchange resins, in particular KU-2-8 cation exchanger - their different types used in these or those situations.

Ion exchange resins (them also call ionites) are the insoluble substances possessing special property. Placed in solution, they are capable to exchange the ions for environment ions. As a rule, synthetic organic resins which are widely used in medicine, in perfumery (for example, for production of soap), and also in chemical industry and for desalting and water treatment concern to them (it is the most important sphere of their application). Though in the nature also natural ionites meet - generally it is some types of clay in which the layered molecular lattice provides quite good production characteristics which can be increased in addition processing by acid or roasting. Such ion exchange resin, thanks to low cost, it is frequent it it is possible only once.

Organic ionites in the nature do not meet, they are synthesized in the industrial way, but possess the increased production characteristics.

Ion exchange resin is subdivided into two big groups - depending on whether absorbs they positively or negatively charged particles. In the first case it is cation exchanger, and in the second - anion exchanger.

Receive these substances from polymeric raw materials. Today very many brands of ion exchange resins are presented at the market, they differ with starting material on the basis of which have been made. The greatest distribution to the industries was gained by the ion exchange resins made from copolymers of divinyl benzene and styrene, and also polyacryle (about 90% of release are the share of them). So receive weak-basic anion exchangers, and also weak and highly acid cation exchange resins.

At each of these versions the scope of application. As a rule, strong-basic anion exchangers are used for water after-treatment, and weak-basic - only in combination with cation exchangers for its desalting. The last can be applied to extraction from solutions of heavy metals, to water demineralizing - and not only to household filters, but also to plants. One of the largest consumers of anion exchangers and cation exchangers are the companies of the power industry in which part of technology process - water treatment.

Ionites — the solid insoluble substances capable to exchange the ions for ions from the solution surrounding them. Usually it is the synthetic organic resins having acid or alkaline groups. Ionites are divided into the cation exchangers absorbing cations, and the anion exchangers absorbing anions. Ionites are widely applied to desalting of waters, in analytical chemistry for division of substances by chromatography method, in chemical technology. Depending on the nature of matrix distinguish inorganic and organic ionites.

Organic ionites are generally synthetic ion exchange resins. The organic matrix is made by polycondensation of monomeric organic molecules, such as styrene, divinyl benzene, acrylamide etc. Ionizable group (the fixed ions) of acid or main type are entered into this matrix by chemical way. Traditionally entered groups of acid type are - SOON; - SO3H; - PO4H2, etc., and the main type: ≡N; =NH; - NH2; - NR3 +, etc. Modern ion exchange resins, as a rule, have the high exchange capacity and stability in work.

Ionites are capable to water regain that is caused by presence of the hydrophilic fixed groups capable to hydration. However boundless swelling, that is dissolution, are interfered by cross bonds. Degree of cross coherence is set at synthesis of ionites through amount of the entered crosslinking agent — divinyl benzene (DVB). The standard pitches used for softening contain 8% of DVB. Pitches available now may contain from 2 to 20%. In general swelling value of ionites is defined by quantity of stitching of DVB, concentration of hydrophilic ionizable group in volume of grain of ionite and what antiions are in ionite. Usually single shot ions, especially hydrogen ions and hydroxyl, lead to the greatest swelling; multiply charged antiions lead to some compression and reduction of volume of grains.

Inorganic ionites are generally ionites of natural origin to which aluminosilicates, hydroxides and salts of polyvalent metals belong. The most widespread and applied to water treatment inorganic natural ionites are zeolites.

Zeolites are minerals from group of water aluminosilicates of alkaline and alkaline earth elements which are characterized by availability of the three-dimensional alyumokremnekislorodny framework forming systems of cavities and canals in which alkaline, alkaline-earth cations and water molecules are located. The total amount of system of cavities and channels of zeolite makes up to 50% of volume of framework of zeolite. Cations and water molecules are poorly connected with framework and can be partially or are completely substituted by ion exchange and dehydration. Ion-exchange properties of zeolites are defined by features of chemical affinity of ions and crystal structure of zeolite. At the same time compliance of the sizes of entrance openings in zeolitic framework and the substituting ions as the framework of zeolite has rigid crystal structure is necessary and unlike organic pitches cannot bulk up with change of volume.

Ion exchange on zeolites has possible to allocate ions which extraction by other method often represents big complexity. Ability of zeolites to adsorb radioactive ions of caesium from solutions, to delete NH4+, to take ions of Cu, Pb, Zn, Cd, Ba, Co, Ag and other metals, to purify natural gases is established. The Ionositovy effect allows to adsorb vapors of nitrogen, CO2, SO2, H2S, Cl2, NH3 from gas and liquid systems. Besides, zeolites can be used for removal of the dissolved iron, manganese and rigidity.

Unlike organic pitches there is number of features of zeolites. So, the general mineralization of the conditioned water has to be not less than 80 mg/l as at the smaller content of salts there is dissolution of silica-alumina framework of zeolite. At rn the conditioned water lower than 6 the probability of destruction of crystal lattice also increases.

Dynamic exchange capacity of zeolites is lower than the dynamic exchange capacity of organic pitches in the same conditions that is connected with slower kinetics of exchange on zeolites. Residual water hardness after zeolites makes about 0,3 mg-ekv/l whereas after organic pitches — no more than 0,1 mg-ekv/l.
