Abstract

To enhance the oxidation of Co(II) by using PbO2 anode and electrolyte emission test for sustainable utilization of electro-scrubbing process is the primary investigation. Introduction of PbO2 electrode on oxidation effect of Co(II) demonstrated an enhanced oxidation efficiency to nearly 20% than Pt coated Ti electrode. The number concentration of the mists generated from the wet scrubber was an about 30 times lower than that of indoor air particles. No change in pH at second scrubber during 24 hr study explains no sulphuric acid escape from the first scrubber or mediated electrochemical solution. These results reveals that this electro-scrubber can maintain its initial concentration of Co(II) and H2SO4 by just adding water and thus becomes a highly sustainable system without losing of H2SO4 and Co catalysts to the environment.
