Thank you all for the information. It is very helpful. I am sure that I am being a pain, but with the manufacturing we end up with some very specific requirements. I can't have copper in the water I send down the drain, so a copper catalyst would be risky for my purposes. The reason I was investigating Sodium Carbonate was that it was inexpensive and presumably didn't make anything hazardous. I mixed them in my lab and is was effective at decomposing the H2O2. I used 35% H202 and washing soda from the grocery store (only $3.99). My main concern at this pont is that the resulting mixture was green. I am not 100% certain that I know what my reaction has produced. I am definitely not an expert, that's why I am looking for information here.
