Degradation of reactive brilliant red K-BP in aqueous solution by means of ultrasonic cavitation was investigated for a variety of operating conditions. It is found that the degradation of reactive brilliant red K-BP in aqueous solution follows pseudo-first-order reaction kinetics and the degradation rate is dependent on the initial concentration of reactive brilliant red K-BP, the temperature and acidity of the aqueous medium. The effects of Fe2+, Fenton reagent and NaCl addition on the sonochemical degradation of reactive brilliant red K-BP were also investigated. The results obtained here indicate that the degradation rate of brilliant red K-BP in aqueous solution was substantially accelerated by Fe2+, NaCl or Fenton reagent addition. (c) 2007 Elsevier B.V.
