Abstract
This paper deals with studying the sonochemical effect for water treatment purposes from the dibenzothiophene (DBT) as polycyclic aromatic sulfur hydrocarbons, one of the most impurities found in waste water coming from petroleum industry. A comparison for the results obtained from previous studies at 20 kHz and with our results at 352 kHz has been done. The influence of organic compounds in the water matrix, as a mixture with dibenzothiophene was also evaluated. The results indicated that some competition occurs in the case of the mixture Bisphenol A/dibenzothiophene. The results presented in this work depict the study of the interesting potential of ultrasound to treat different types of water contaminated with polycyclic aromatic sulfur hydrocarbons such as dibenzothiophene and comparison for the degradation profile with benzothiophene which explained previously by us.
