Separation of Iron Chlorides

encipher - 8-10-2010 at 08:09

Hello All,

I was wondering what would be a good way to separate ferrous chloride (undesired) at a concentration of 2.9 w/w % from a solution containing 36.9 w/w % ferric chloride. Would a magnetic separator work, given that ferrous chloride is paramagnetic and ferric isn't? Or is there a better way perhaps?

Thanks!

Iron (II) is easily oxidized to Iron (III). Perhaps add some HCl and bubble air through the solution. Chlorine gas will also oxidize it.
