| 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 ), n 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, n said anode ( 5 ) creating positive ions and electrons, n said electrolyte ( 7 ) allowing the transfer of a positive charges, n 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. |
