Effect of Microwave Assisted UV Electrodeless Discharge Lamp Photocatalysis on Degradation of Methyl Orange

摘要

A microwave assisted untraviolet system (MW/UV)was used for of degradation methyl orange.Results showed that the degradation rate in MW/UV/TiO2 system was higher than those in MW/TiO2 system and MW system within 150min which were 54.8 %, 15% and 13.5% respectively.Cu doping could improve the degradation rate in the microwave assisted untraviolet system (MW/UV) and Cu0.6/TiO2 showed the highest degradation rate.When Cu0.6/TiO2 concentration was 0.575 mg/L, and pH was 3.5 of the degradation time 150 min,degradation rate could reach 62.4%.XRD characterizing indicated that Cu doping blocked the transformation from anatase to rutile and reduced the particle sizes.
