Degradation of Tetracycline by Eletrochemical Oxidation Using Dimensionally Stable Anode

As an emerging pharmaceutical and personal care products (PPCPs), tetracycline was selected as a model pollutant for electrochemical oxidation using commercial DSA. The effect of electrode potential across the anode and cathode and those of sodium sulphate and sodium chloride were investigated. It demonstrated that the increase of the potential across the electrodes from 4 V to 12 V improved the decolorization efficiencies as well as the COD removal steadily. The presence of electrolyte such as sodium sulphate and sodium chloride had dramatically enhanced the degradation of tetracycline, in which 83.6% of decolorization and 42.6% of COD removal were achieved by 240 min.
