| Abstract: | In this study,a phenol wastewater was treated by the combined process of independent photocatalysis and electrolysis.Based on the analysis of the reaction kinetics and the mechanism of combined degradation,the influence of NaCl dosage,current density and pH on the degradation rates was investigated.The results showed that the synergetic enhancement effect was produced in the combined process,and promoted significantly in the presence of sodium chloride.The combined degradation of phenol followed the pseudo-... |
