Electrochemically assisted decomposition of ozone for degradation and mineralization of Diuron

In this work, we explore the possibility of enhancing the ozonation of a solution of Diuron by combination with electrochemical processes. To this aim, the ozonation was performed in a membrane free electrolyzer where a reticulated vitreous carbon (RVC) and a stainless steel (SS) cathode have been alternatively tested and compared. The effect of pH, current density and ozone flow on degradation and mineralization of Diuron has been investigated. The involvement of radical species has been verified by means of test conducted with selective scavenging agents.
