THE DEGRADATION OF RESIDUES OF DRUGS IN WASTEWATER USING PHOTOCATALYSIS WITH TITANIUM DIOXIDE

Popis výsledku v původním jazyce

This work is focused on the use of heterogeneous photocatalysis for treatment of wastewater containing ibuprofen and paracetamol as model drugs. The aim was to achieve such concentrations of drug residues in water, which no longer pose risk to the environment and living organisms. Studying photolysis of ibuprofen, it was found that the substance decomposes under UV radiation even without using catalyst. Addition of TiO2 catalyst in a concentration of 1 g/L and the use of O2 as oxidizing agent practically did not increased rate of photolysis. When using hydrogen peroxide and the concentration of TiO2 1 g/L a complete mineralization of the sample of ibuprofen was achieved . When studying the photolysis of paracetamol, it was found that the substance didpractically not decompose without the use of a catalyst and at constant oxygen concentration. Using hydrogen peroxide it was observed only slow decrease in the concentration of paracetamol. The use of TiO2 and oxygen had practically no in
