The effect of SbCl3 adding amount and sintering temperature on its electrode lifetime and oxygen evolution potential were investigated by means of EDX, SEM and XRD analysis. The results indicated that the electrode appeared the best performance when the SbCl3 adding amounts was 0.2g and the sintering temperature was 550℃. In optimized conditions Ti substrate was entirely covered by SnO2 Sb2O4 and the combinations among them were tight. Due to the use of electroplate method, the electrical conductivity, the oxygen evolution potential and the electrode lifetime were increased, so the electro catalytic activity and the electrochemical stability of the prepared electrode were found to be superior.展开更多

The electrolysis reaction conditions were optimized. The process of electrochemical decomposition was monitored by ultra-violet spectrophotometry and CODCr method. The electrochemical decomposition mechanism of imazethapyr was studied primarily by UV-VIS spectrophotometry. The effectiveness of the electrochemical pretreatment was proved by the comparative aerobic biological treatment test based on the activated sludge process.展开更多
