Ligands specific for divalent ions
« on: January 17, 2006, 01:47:52 AM »
Does anyone know of a ligand that is specific to divalent ions?  I have aqueous solutions containing both divalent and trivalent cobalt and need to selectively chelate *either* the divalent cobalt or the trivalent cobalt (so a ligand that specifically chelates trivalent ions would work, too).  I need to be able to selectively remove either Co(II) or Co(III) from solution without altering its oxidation state.  Any suggestions are welcome!  Cheers,  :)

Can you use a cation exchange resin?

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

What about BOX and PyBOX ligands?
