Deionize

Water can be deionized using ion exchange resins.

Sparks have been made with durations as light sources down to a few nanoseconds, the advantage being that the ionized gas which created the light can deionize and dissipate its heat sufficiently quickly whereas a discharge in gases like xenon in a bottle deionizes and dissipates more slowly.

In the acidic medium at pH 2.0, amino, imino and hydroxyl groups of the hybrid are protonated and KP [ketoprofen] deionizes and becomes less soluble [36]; this leads to a decrease in the release rate and percentage of KP.
