Abstract
Apparatus and method for photo-chemical oxidation are disclosed herein. In one embodiment, a method for regenerating a dialysis fluid includes: flowing the dialysis fluid between an anode and a cathode of a dialysis system, where the anode comprises a plurality of nanostructures; illuminating the anode with a source of light; flowing oxygen through the cathode toward the dialysis fluid; and converting urea in the dialysis fluid into CO2, N2 and H2O thereby regenerating the dialysis fluid.
Claims18
A method for regenerating a dialysis fluid, the method comprising:
- flowing the dialysis fluid between a photo-electrochemical anode and a cathode of a dialysis system, wherein the photo-electrochemical anode comprises a plurality of nanostructures, and wherein the cathode is permeable to oxygen provided to the dialysis fluid and non-permeable to a liquid of the dialysis fluid;
- illuminating the photo-electrochemical anode with a source of light;
- flowing the oxygen through the cathode toward the dialysis fluid;
- and
- converting urea in the dialysis fluid into CO2, N2 and H2O through a photo-electrochemical reaction thereby regenerating the dialysis fluid.
