Abstract:
1. A device for decaffeinating a liquid, the device comprising: at least one cathode electrode and at least one anode electrode spaced apart from one another and being immersed in the liquid; and a power supply coupled to the at least one cathode electrode and the at least one anode electrode and configured to apply a power thereto, wherein the at least one cathode electrode and the at least one anode electrode are configured to generate an electrical field in the liquid upon application of the power to attract caffeine molecules in the liquid to the at least one cathode electrode, wherein the at least one cathode electrode is made of or coated with an absorbing material configured to absorb at least part of the caffeine molecules that are attracted to the at least one cathode electrode, said absorbing material comprises one of porous carbon material, conductive polymer and inorganic adsorbent.
