| Abstract: | PbO2/Ti anode and foam Ni cathode were used in electrolysis of acid red 18(AR18) solution.Voltage,current,electrolyte concentration and pH that affected electrochemical degradation of AR18 was studied without ion exchange membrane.Simultaneously,we analyzed the correlativity between remnant concentration of AR18 and electrolysis time.The results showed that the degradation of AR18 was consistent with first-order kinetic.In the experiment appending ion exchange membrane,we analysed the UV-Visible spectrum da... |
