Ion Exchange Column Question
« on: Today at 05:17:20 PM »

Hello,

I have a quick question regarding elution when it comes to an anion exchange column.  In a lab I was doing, both 9M and 4M HCl were used to elute Ni in the form NiCl+ and Co in the form CoCl+ respectively.  My question is whether or not something like KCl could be used instead of this HCl for the purposes of elution (would the KCl be able to provide the necessary source of chloride, in essence)? 
Any help would be appreciated!

If it is the anion exchange column it was H+, not K+, that is important for the exchange. Cl- complexes the metal cation, but it is not that important effect.
