| Abstract: | A MW-UV reactor was developed indigenously for
degradation of aqueous phenol and m-cresol (degradation efficiency, MW-UV-TiO2 >
UV-TiO2 > MW-TiO2 > MW-UV > UV > MW). Maximum
degradation of phenol (85%) and m-cresol (92%) by MW-UV-TiO2 and MW-UV-TiO2 was three folds faster in
reaction time and catalyst requirement than UV-TiO2 method.
Degradation of phenol and m-cresol in
reactor followed pseudo first order reaction and reaction rate (k) for
MW-UV-TiO2 was 2.2 times greater than UV-TiO2 and greater
(17 times for phenol and 22 times for m-cresol)
than other processes. MW-UV-TiO2 was 2.3 times more efficient in removal of TOC than conventional photocatalytic method. |
