As a chemist, I somewhat agree. If something was becoming not ionized, I’d say deionization. But generally I’d go with non-ionized.
Edit: I was pretty tired when I posted the original message. But after looking back, if something was non-ionized, I’d probably just say “neutral”, since it probably doesn’t have a charge.
I think de-ionize or de-ionized/de-ionization is the proper term.

I agree with the professional chemist.
As a plumber, I respectfully disagree.
