Subcritical mineralization of sodium salt of dodecyl benzene sulfonate using sonication—wet oxidation (soniwo) technique

Subcritical mineralization of sodium salt of dodecyl benzene sulfonate via hybrid process—sonication followed by wet oxidation (SONIWO) has been investigated. Sonication of the compound enhanced the rates and % COD reduction during wet oxidation. In this process, homogenous CuSO4 catalyst was found to be effective. In wet oxidation studies, phenol, hydroquinone, maleic acid, oxalic acid, propionic acid, and acetic acid were identified as intermediates. The global rate equations for wet oxidation in terms of COD reduction were developed.
