Enhanced degradation of paracetamol by combining UV with electrogenerated hydrogen peroxide and ozone
The in-situ production of highly oxidizing species represents a sustainable approach for the treatment of unregulated emerging contaminants. In this article, we investigate the UV induced degradation and mineralization of paracetamol that represents one of the most frequently prescribed and sold drugs worldwide. In particular, this work compares two advanced oxidation processes based on photolysis of electrogenerated hydrogen peroxide (H2O2), and ozone (O3). The H2O2 electrosynthesis has been performed via oxygen reduction on gas diffusion electrodes (GDE).
