| abstract |
The invention relates to an apparatus for purifying fluids comprising at least one electrochemicalncell 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 representsnan organic or inorganic ligand, said complex being capable of forming the hydroxylnradical by a reaction wherein the metal in the complex is oxidised and acquires an additionalnpositive 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 thenmetal complex on the cathode. The invention also provides a related electrode and a relatednelectrochemical cell as well as a corresponding method for purifying fluids. |
