Hello all,
I have used Amberlite IRC120 H, hydrogen form acidic cation-exchange resin for the ion-exchange of waterglass [sodium silicate solution -- 40% Sodium silicate (mol ratio > 3.2) & 60% water]. I did not dilute the waterglass any further prior to ion-exchanging (big mistake) and it cross-linked so that the resin has now become a solid block. Any suggestion on how to dissolve the cross-linked resin? I just want to use the column again, which is not functional any longer due to the hardened resin within it.
Thanks in advance for your advice.

I would not recommend to try and recover the resin for reuse. I guess the properties will have changed irreversibly so you better replace it by new resin
Thanks for your answer Frank. Yes, I also think that the cross-linked resin is not useful anymore. The issue is that it is currently within the column and I would need to remove it from it in order to use the column again. Any ideas on how to dissolve cross-linked Amberlite IRC120 H, hydrogen form acidic cation-exchange resin so that it can be removed from the column?
Thanks.
Max D.
we are used to dissolve strong cation resins for determination of nitrogen content of the resin (as a measure of resin fouling). This is done by putting dried resin in concentrated sulphuric acid, slowly heating until boiling and maintaining these conditions for some hours. I wonder if your column would resist similar conditions
