Sažetak
Pharmaceuticals in wastewaters can not only cause environmental deterioration but adverse health effects on human as well. They are often hardly biodegradable and physicochemical technologies are required for their removal from water, albeit they are usually of limited effectiveness. Among possible solutions for the degradation of organic pollutants in wastewater is heterogeneous photocatalysis. In this work, photocatalytic treatment of ibuprofen, amoxicillin and ciprofloxacin by UVA/TiO2 process were studied. The experiments were performed in suspension, at pH values from 4 to 10 and TiO2 mass concentrations from 0.2 mg/L to 2 mg/L. The removal and conversion extents of the aforementioned pharmaceuticals during photocatalytic treatment were monitored by HPLC. Optimal photocatalytic parameters were determined by Full Factorial Design (FFD) based on two variables, pH and mass concentration of applied photocatalyst, combined with RSM approach. Analysis of variance and statistical parameters were determined by Design Expert and Statistica software packages. The use of this approach enabled simple and fast detection of influential process parameters, and provided system optimization within the tested range of process parameters.
