To remove ions from a substance, especially water, using chemical or physical methods to make it purer.
From the prefix 'de-' (remove) combined with 'ionize,' which comes from Greek 'ion' (moving thing), literally meaning to reverse ionization.
Deionizing water was a game-changer in science and industry because even tiny amounts of dissolved salts can ruin experiments or corrode sensitive equipment.
