Abstract
Sono-degradation and sono-enzyme degradation of phenols were performed on the mixtures of double compounds (phenol,
p-chlorophenol; phenol,
p-cresol; phenol,
p-nitrophenol; and
p-chlorophenol,
p-cresol) in aqueous medium. Sono-degradation of phenol and its substituted compounds individually behaved approximately the same, but in the case of mixture behaved differently. Sono-degradation of substituted phenols was easier than phenol in a mixture, but there was an exception in the combination of phenol and
p-nitrophenol that the degradation of phenol was faster than substituted compound. This behavior was the same in sono-enzyme degradation, but with higher degradation rate. Between these mixtures, the combination of phenol and
p-cresol presented a significant different behavior in case of single and double compounds solutions. In this system, the sono-degradation of phenol in mixture was more difficult than phenol alone but, the sono-degradation of
p-cresol in mixture was easier in comparison with
p-cresol alone. In sono-enzyme degradation,
p-cresol as a more reactive compound facilitated the remove of phenol in mixture in compare of the individual case.
