The photodegradation of chlorodifluoromethane (HCFC-22) was investigated using microwave/UV/TiO2 photocatalysts hybrid system. The microwave discharge electrodeless mercury lamp (MDEML) used in this study showed mainly atomic Hg emission lines at 253.7 nm. The decomposition efficiency of HCFC-22 increased with decreasing inlet concentration and with increasing reactor residence time. The removal efficiency increased with increasing microwave power on every oxygen concentration. The highest degradation efficiency was obtained when both TiO2 balls and MDEML were used.
