deionization

[dē‚ī·ən·ə′zā·shən]
(chemistry)
An ion-exchange process in which all charged species or ionizable organic and inorganic salts are removed from solution.
(electronics)
The return of an ionized gas to its neutral state after all sources of ionization have been removed, involving diffusion of ions to the container walls and volume recombination of negative and positive ions.

cation-exchange softening

The softening of water by the removal of dissolved ionic contaminants in hard water (such as scale-forming magnesium and calcium ions) and their replacement with sodium ions, which are more soluble.
