A series of Ti-coated electrodes (also known as Dimensionally Stable Anodes, DSA electrodes) are prepared which were modified by doping Pd, Co, Si and introducing Sn-Sb intermediate-layer into the RuO2/Ti electrode, in order to enhance the electrochemical properties and service-life of the electrode. These modified electrodes are used as anodes in electro-catalytic reactor to degrade Nitrobenzene (NB) which is difficult to be biochemical degraded. The optimum technological parameters of wastewater treatment...
