The Degradation Kinetics of Phenol Solutions with Ozone

Aromatic compounds are extensively used in several of industries and can cause pollution in water sources. This work aims are to examine the degradability by cleavage of phenol in aqueous solutions using ozone, and to determine the kinetics of those cleavage reactions. Phenol has been prepared in four different concentrations and the flow rate of ozone supplied for each solution has been selected. The reaction of ozone with phenol was investigated at several conditions, such as different phenol and ozone concentrations, and contact times. Total Organic Carbon (TOC) and UV analysis of the aromatic by-products formed during and after the ozonation reaction were employed. The reaction rates calculated from TOC analysis were investigated.
