Enhancement of the Advanced Fenton process (Fe0/H2O2) by ultrasound for the mineralization of Phenol

In this study, a successful mineralization of phenol was achieved by means of coupling zero-valent iron (ZVI) particles, hydrogen peroxide and a short input of ultrasonic irradiation. This short Sono-Advanced Fenton process (AFP) provided a better performance of ZVI in a subsequent silent degradatio...
