Sono-photocatalytic degradation of 2-cholorophenol in water: kinetic and energetic comparison with other techniques

The degrdn. of 2-chlorophenol in water was kinetically investigated using the following different techniques, employed either sep. or simultaneously, always with the same exptl. set-up: light irradn. (315-400 nm), sonication, photocatalysis with different types of TiO2, photocatalysis with sonication. The influence of the reaction vol. and of different gas mixts., contg. Ar and O2, as well as O2/O3, was also investigated. Finally, an energetic comparison among these different techniques was performed, focused on an industrial application of some of them.
