I have an interesting situation in which I need to find out how to immobilize calcium but retain its activity. Google just pulls up Sodium Algenate and Calcium Chloride is used in the last step to harden the beads. That's not going to work. I'm wondering if I could possibly charge calcium onto a sheet and have it stay there in water or if someone knows of a method I could try that would allow me to reuse the calcium.

calcium metal, calcium ions? what reaction are you trying to do with the "calcium"?

 

I'm assuming you don't mean calcium metal because you say you want it to stay there in water...

 

more info required

Calcium Ions.

 

I'm trying to get them to work like an enzyme and not get consumed. I'm doing a precipitation and it works with a lot of calcium added to solution however I want to do it using the calcium in the solution BEFORE I add it that way I can reuse the calcium I added again and again.
