Apparatus and method for urea photo-oxidation

Abstract

Apparatus and method for photo-chemical oxidation are disclosed herein. In one embodiment, a dialysis fluid regeneration system comprises: a nanostructured photo-electrochemical anode configured for illumination by a source of light. The system further comprises a cathode that is permeable to oxygen provided to a dialysis fluid and non-permeable to a liquid of the dialysis fluid. The photo-electrochemical anode is configured to be in contact with the dialysis fluid, and configured to regenerate the dialysis fluid by converting urea in the dialysis fluid into CO2, N2 and H2O through a photo-electrochemical reaction.
