Ion exchange resins use a process based on ion selectivity. In this method, ions of greater preference will displace ions of lower preference. For example, in water softening, objectionable ions such as calcium and magnesium are ex- changed onto the resin and sodium or potassium ions are released in their place.
If the exchanged ions are positive, the exchange material is called cationic, and anionic if the ionic species have a negative charge. Cations, such as calcium, magnesium, barium, strontium and radium, can be separated from an aqueous solution by using a cation-exchange resin.
