I suppose that would depend on exactly what ions we are talking about.
I was just going by the idea of ions in general, since these “anti-ion” devices never seem to make any distinctions. Na+, UH-. . .it’s all the same to them, apparently.
Come on you guys do not know what you are talking about. You have positive or negative ions that surround you everyday. Every and any Atom can be a positive or negative Ion.
In theory, yes. In reality, no. Atoms don’t usually just go around shedding or gaining electrons for no reason. So certain atoms tend to form certain ions in certain situations. And of course metals tend to form cations while nonmetals form anions due to their relative ionisation energies.
You could remove all (or at least a very great many) of the ions from your body by getting into a giant anode/cathode device and ripping them all from your body. It would not be a very good idea, though, and would be rather messy as it would involve ending all nerve function and disassembling cell walls and the like. That probably wouldn’t do much against anions that are bonded to a balancing cation charge, though, other than to line them all up nearly parallel by polarity. . .which would perhaps do very weird things to the body, I suppose. But those probably wouldn’t be the sorts of ions that these people are fussing about, since they’re neutral on a molecular level. I think that they’re raving about unbonded ions.
Or you could get rid of most positive ions by bombarding yourself with a huge stream of electrons. Again, that wouldn’t be a very good idea.
And in either case, your shredded remains would ionise again in a short amount of time.
