Ion exchange is an exchange of ions between two electrolytes or between an electrolyte solution and a complex. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic 'ion exchangers'. Ion exchangers are natural substances-for example, certain clays or deliberately synthesized resins containing positive ions (cation exchangers) or negative ions (anion exchangers) that exchange with those ions in solution having a greater affinity for the exchanger. This selective affi...

Ion exchangers are natural substances-for example, certain clays or deliberately synthesized resins containing positive ions (cation exchangers) or negative ions (anion exchangers) that exchange with those ions in solution having a greater affinity for the exchanger. This selective affinity of the solid is called ion, or ion-exchange, chromatography.
