The degradation of p-nitrophenol (PNP) in a three-electrode cell with a sandwich bath but without any diaphragm was studied by galvanostatic electrolysis using the Ti/PbO2 electrode as an anode and the titanium plate as a cathode. The optimal conditions of temperature, pH, current density and initial concentration of PNP were determined by an orthogonal experiment. The change of degradation ratio with the above factors was discussed by changing single factor experiment. The results indicated that the effect order of the factors on the degradation ratio of PNP was PNP initial concentration >; temperature >;current density >; pH in the electrolyte; the optimal conditions of PNP degradation by electrocatalytic oxidation was: the initial concentration of PNP was 1.0 mmol-L-1, pH in the electrolyte was 2, the temperature was 55°C and the current density was 80 mA-cm-2. Under the above conditions, the degradation ratio of PNP can reach 98.00% after 2.5 h electrolysis.
