Abstract:Experimental study on microwave assisted photocatalytic degradation of phenol in aqueous solution was carried out with modified domestic microwave oven, electrodeless discharge lamps (EDLs) and TiO2 catalyst. Results showed that the removal rate of phenol in the MAPC process was 92% after 30 min reaction. Loss of total organic carbon (TOC) was 84% . The optimal conditions for the MAPC method were 10 mg/L phenol, 900 W MW output energy, 50 mL solution volume, EDLs-3, 1-4 g/l. catalyst dosage and 15 mL/min of flowing velocity in the circulating mode. The MAPC process was promising in treating phenolic waste water.
Keywords:microwave assisted  photocatalysis  degradation  phenol
