Sonochemical degradation for toxic halogenated organic compounds

This paper describes the degradation of p-chlorophenol using three differen t ultrasonic devices. The dissipated power in the reaction matrix was measu red based on calorimetric method. The study showed that hydrogen peroxide c an improve the sonochemical reaction and gases dissolved in reaction matrix can affect the process to a small extent. The reaction mechanism and kinet ics of degradation were also investigated. (C) 2001 Elsevier Science B.V. A ll rights reserved.
