Abstract
The aim of this work was to evaluate the influence of mineral and organic matrices on the sonochemical degradation of 4-isopropylphenol (4-IPP), an endocrine disrupting chemical found in water. Bicarbonate ions as mineral matrix and sucrose as organic competitor were evaluated with respect to their effect on sonochemical degradation rates. At low 4-IPP concentration, the sonolytic degradation was clearly improved in the presence of bicarbonate involving the formation of the carbonate radical resulting from the reaction of bicarbonate with hydroxyl radical. In the presence of large excess of sucrose, the sonochemical degradation of 4-IPP at low concentration was not affected.
