I'm looking to make a CO2 scrubber for a school project and I was wondering if I can purify water to re-use it with magnetic fields. The ions would be K+ and CO3-2.

If this can be done can you explain what variables I have to look into to make sure it works, some variables I thought of was attration of ions and water, force of water flow, and the type of magnet used.

If you can give me your feedback and advice that would be great! Thanks!

Yes, but no.

Yes - moving charges in the magnetic field are shifted to sides (google for Lorentz force), no, forces acting on these charges are way too low to be used for practical desalination.

Is it possible to make the force great enough?

No, you won't be able to produce magnetic fields strong enough.

Ok what about positive and negatively charged plates?

Same problem, just with the electric field.

See http://en.wikipedia.org/wiki/Deionization for methods that are known to work.
