Sažetak
In this research degradation of atrazine from simulated groundwater by ozonation itself and the combination of ozone and UV photocatalysis using TiO2 have been investigated. It has been found that atrazine was degraded by photolysis alone but no reduction of TOC content has been noticed. However, with TiO2 photocatalyst involvement the rate of degradation has increased in comparison with photolysis itself. Reduction of TOC content was observed, too. Concerning preliminary results it has been found that ozonation itself was the most efficient in the pH range from 6 to 11. Ozonation process enhancement was achieved by introducing of UV irradiation into the system. The use of TiO2 photocatalyst in the UV/O3 process slightly improved the overall performance. For all studied processes kinetics of atrazine degradation was monitored.
