How can ion exchange resins be transformed?

Taking the most commonly used strong-acid cation exchange resin 732 for boiler water treatment as an example, for ease of transportation and storage, it is available in both hydrogen-type and sodium-type forms upon leaving the factory. 　In practical use, it often switches to other ionic forms to meet various requirements. For example, strongly acidic cationic resins are often reacted with NaCl to be converted into sodium-type resins for further use. During operation, the sodium-type resin releases Na+ to exchange and adsorb cations such as Ca2+ and Mg2+ in the solution, thereby removing these ions. No H+ is released during the reaction, which prevents a decrease in the solution’s pH and the resulting side effects (such as sucrose conversion and equipment corrosion). After being used in sodium form, this resin can be regenerated with brine (without strong acids). After being converted to the sodium form, strongly acidic resins no longer possess strong acidity or alkalinity, but they still retain other typical properties of such resins, such as high dissociation strength and a wide operating pH range.
