Re-gaining rhodium

I have water has been used in rhodium bath. Can I re-gain rhodium from this water or how can I make this water usable again?

Hello, Cengiz. Commercial ion exchange cylinders are readily available that will capture the rhodium and allow you to re-use the water for additional rinsing. Usually they are applied on a continuous basis, with the rinse water constantly recycling through them. When the ion-exchange capacity is exhausted, the resin is sent to a refinery for burning to recover the rhodium values.
