Ion-exchange resin - Wikipedia
WEBAnion resins and cation resins are the two most common resins used in the ion-exchange process. While anion resins attract negatively charged ions, cation resins attract positively charged ions.
WEBIon exchange resins have been classified based on the charge on the exchangeable counterion (cation exchanger or anion exchanger) and the ionic strength of the bound ion (strong exchanger or weak exchanger). Thus, there are four primary types of …
Ion Exchange & Water Demineralization Handbook | Veolia
WEBOxidants attack the divinylbenzene cross-links in a cation resin, reducing the overall strength of the resin bead. As the attack continues, the cation resin begins to lose its spherical shape and rigidity, causing it to compact during service.
WEBTo soften water, you take a cation exchange resin on which the mobile ion inside the beads is sodium (Na + ) and you pass the hard water through a column filled with the sodium form resin.

Understanding Ion Exchange Resins: - Ionic Systems
WEBA common ion exchange resin can replace those calcium ions with sodium ions. The process involves passing the water through a column filled with resin beads. As water contacts the beads, the unwanted ions are captured, and in their place, ions from the resin are released into the water.
WEBA cation exchange resin with a negatively charged matrix and exchangeable positive ions (cations) is shown in Figure 1. Ion exchange materials are sold as spheres or sometimes granules with a specific size and uniformity to meet the needs of a particular application. The majority are prepared in spherical (bead) form, either as conventional ...

WEBCation resin is a negatively charged matrix with exchangeable positive ions (cations). Negatively charged ions are fixed and permanently attached – part of the resin structure. Because the bead is negatively charged only positive ions are attracted or exchanged.
Anion vs. Cation Ion Exchange Resins - WaterProfessionals
WEBCation resins naturally attract a certain set of minerals, while anion resins attract another set of minerals. The polymeric resin beads are treated such that they contain thousands of tiny cracks, thus increasing their surface area.
Ion Exchange (IX) - DuPont
WEBIon exchange is the reversible interchange of ions between a solution with soluble ionized substances and a solid (the ion exchange material, such as a cation resin), in which there is no permanent change in the structure of the solid.

Cation Exchange Resin - an overview | ScienceDirect Topics
WEBA bead of ion exchange resin is comprised of 3 units: an insoluble matrix, to which fixed ionic sites (functional groups) are attached, and an equivalent number of counterions that will be involved in the exchange process ( Fig. 2 ). Resins can be purchased with either anion, cation or mixed (amphoteric) counterions.
What Is the Difference Between Cation and Anion Exchange Resins?
WEBCation and anion exchange resins are both small, porous, plastic beads (approximately .5 mm diameter, which varies) that are fixed with a specific charge. This “fixed” charge cannot be removed and is part of the resin’s crosslinked makeup or structure.
What is Regeneration | Purolite | www.purolite.com
WEBRecycling between cation resin and anion resin will remove any remaining regenerant chemical. After rinsing, the resin bed is returned to service. The total time to regenerate is < 2 hours and the total water used is about 7 x the resin volume: 15L bed = 105L (50 gal./ft 3). The wastewater is discharged.
