Monopolar electrodes Electrode oxygen

In the domain of food industries, EED was used to reduce oxygen in fruit juice [46], to extract cytoplasmic proteins from alfalfa [47,48], to coagulate proteins [49], and to reduce disulfide bonds in proteins [50]. These applications are based on the electrode redox reactions coupled with monopolar membrane action. 

The technology of these etectrowinning processes is very simple, The cells are open OD iele tanks lined with rubber or plastic and the lines of anode and cathode plates are placed alternatively with a separation of 5 15 cm the cells are connected monopolar and one arrangement is shown in Fig. 4.S, The anodes are lead alloy sheets which in the sulphate medium form a lead oxide coating the metal additions to the lead (c.g. silver) arc to catalyse oxygen evolution and therefore reduce the anode overpotentiaL The starter sheets for the cathodes are aluminium or titanium and the metal is deposited until there is a layer 3-5 cm thick, at which point the cathodes are removed from the cell. The metal is then Stripped from the starter sheets and these are reused. The electrodes are typically Q,3-0.5 m in area but the anodes are always larger than the cathodes to prevent...
