Abstract

The invention relates to an apparatus for purifying fluids comprising at least one electrochemical cell having a cathode (3), an anode (5) and an electrolyte (7),said cathode (3) comprising a metal complex, ML, where M represents a metal and L represents an organic or inorganic ligand, said complex being capable of forming the hydroxyl radical by a reaction wherein the metal in the complex is oxidised and acquires an additional positive charge,said anode (5) creating positive ions and electrons,said electrolyte (7) allowing the transfer of a positive charges,said cathode being arranged such that the fluid to be purified can come into contact with the metal complex on the cathode. The invention also provides a related electrode and a related electrochemical cell as well as a corresponding method for purifying fluids.
