Abstract:
An apparatus for purifying fluids comprising at least one electrochemical cell having a cathode, an anode and an electrolyte between said cathode and anode, said anode creating positive ions and electrons, said electrolyte allowing for the transfer of positive charges, said cell further comprising a catalyst for promoting a reaction creating the hydroxyl radical, said catalyst being immobilized in or at a solid located at the cathode side of the cell, said solid being arranged such that the fluid to be purified can come into contact with the catalyst, wherein said catalyst is a metal complex, ML, wherein 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 oxidized and acquires an additional positive charge.
