Strong acidic cation resin
This type of resin (IONRESIN) contains a large number of strong acidic groups, such as sulfonate-SO3H, which easily exjects H-plus in the solution, so it is strongly acidic. After resin dissotion, the negative cell, such as SO3-, contained in the body, can adsorption other cations in the binding solution.
These two reactions cause the H-plus in the resin to exchange with the cations in the solution. Resin after a period of use, to carry out regenerative treatment, that is, the use of chemicals to make ion exchange reaction in the opposite direction, so that the resin's can-power group to restore the original state for reuse.
Such as the above-mentioned cation resin is regenerated with strong acid, at this time the resin releases the adsorption of the cation of the cation of the cation of the cation, and then combined with H-plus to restore the original composition.
Weak acidic cation resin
This type of resin (IONRESIN) contains weak acidic groups, such as argon-COOH, which can be extracted from the water by H-plus and are acidic. The remaining negative celludes, such as R-COO-(R is the hydrocarbon group), can be combined with other cation adsorptionof to other cations in the solution to produce a cation-swapping effect. The acidity of this resin is weak, it is difficult to dissote and exchange ions at low pH, and can only function in alkaline, neutral or microacidsolutions (e.g. pH5-14).
