<p>Purification apparatus for the continuous electrolytic purification of solutions utilised in electro-deposition treatments and the like includes one or a plurality of cells comprising a bowl (8) containing substantially flat closely spaced anodes (2,2 min ) and at least one cathode (3) having means (3 min ) for determining the inter-electrode separation housed sealingly within a chamber defined by the bowl (8) and a cover (12) and forming a sinuous path for fluid supplied through the cover (12) to pass between the electrodes. The provision of flat closely spaced large-area electrodes allows the current density and electrolytic action to be closely controlled and maximises the available contact area of electrode for the deposition of, for example, unwanted metal ions.</p> |
