Photocatalytic ozonation of monuron over suspended and immobilized TiO2

Heterogeneous photocatalysis, using photocatalyst in suspensions and in immobilized form, ozonation, and their combination (photocatalytic ozonation) at various ozone (O3) concentrations (0–20 mg dm–3 O3 in gas phase) were investigated and compared in the transformation of the herbicide monuron (3-(...

520 3 |a Heterogeneous photocatalysis, using photocatalyst in suspensions and in immobilized form, ozonation, and their combination (photocatalytic ozonation) at various ozone (O3) concentrations (0–20 mg dm–3 O3 in gas phase) were investigated and compared in the transformation of the herbicide monuron (3-(p-chlorophenyl)-1,1-dimethylurea). Using the photocatalyst (Aeroxide® P25) in immobilized form, the rate of transformation of monuron was considerably lower compared to the case of suspension (1.0 g dm–3 TiO2). O3 increased the rate of transformation in each case, while the photocatalyst decreased the concentration of dissolved O3. However, there was no synergistic effect during the combination of heterogeneous photocatalysis and ozonation. The economic feasibility of the treatments was also compared based on the obtained values of Electrical Energy per Order (EEO). The EEO value decreased with the increase of O3 concentration in each case, and there was no significant difference between the energy requirement of ozonation and its combination with heterogeneous photocatalysis using TiO2 in suspension at each O3 concentration.
