Displacement of one ion by another. Cations and anions can be exchanged between a liquid and a solid exchange medium. Cation, or base exchange, can be used to soften a water. Cation and anion exchange are both used in preparation of boiler feed water...

The process of replacing one ion that is attached to a charged surface with another. A very important type of ion exchange is the exchange of cations bound to soil particles. Soil clay minerals and organic matter both have negative surface charges that...

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...
