Ion cation exchange

Ammonia NH3 Corrosion of copper and zinc alloys by formation of complex soluble ion Cation exchange with hydrogen zeolite, chlorination, deaeration, mixed-bed demineralization... 

An improved synthesis of D-psicose from base-catalysed isomerization of D-fructose using calcium ion cation-exchange resin chromatography has been reported. 

In the field of microbial products, the rhamnolipids 1 have been analysed by reverse phase methods, and 2-0-a-D-glucopyranosylglycerol, a cyanobacterial osmolyte , has been analysed in the presence of several disaccharides, sugars and alditols. In the latter case reverse phase and calcium ion cation exchange resin colunms were used. ... 

Figure 4 Hydration in the system single charged lysine ion - cation exchanger with (left) and without (right) sterio restrictions. The schemes have been designed on base of IRS data for gel KU-2-8 and macroporous KU-23 (30/100) materials correspondingly. The angles between drown bonds are not representative...

AMP-1 4.0 Microcrystalline ammonium molybdo-phosphate with cation exchange capacity of 1.2 mequiv/g. Selectively adsorbs larger alkali metal ions from smaller alkali metal ions, particularly cesium. 

Carboxylate exchangers contain —COOH groups which have weak acidic properties and will only function as cation exchangers when the pH is sufficiently high (pH > 6) to permit complete dissociation of the —COOH site. Outside this range the ion exchanger can be used only at the cost of reduced capacity. 

Ion-Exchange Equilibrium. Retention differences among cations with an anion exchanger, or among anions with a cation exchanger, are governed by the physical properties of the solvated ions. The stationary phase will show these preferences ...
