 of different lactose solutions (0, 00, 00, and 00%) at different current intensities (000, 000, and 000 mA) is shown in [Figure [0](#fig0){ref-type="fig"}](#fig0){ref-type="fig"}. The ORP values in the cathodic compartment were decreased drastically to a value of around −000 mV within the first 0 min of
