Does anyone have experience regenerating the ascorbic acid used as reducer? The composition of the solution is DHAA, PVP, DHAA and nitrate (from copper nitrate). How can I treat this solution to have it ready for another reduction (i.e. reuse of the solution)?

You would have to add a reducing agent that is stronger than the DHAA such as sodium borohydride, however you would then have borate salts remaining the solution, which could potential effect the production of nanoparticles.
