Originální abstrakt

In recent years, there has been an increasing interest in occurrence of hormonal substances in aquatic ecosystems. Attention is paid especially to estrogens (female sex hormones). In this study we focused on assessment of TiO2 photocatalysis to remove natural estrogen estriol. Photocatalytic experiments were conducted in a glass circulated reactor with a rotary holder of immobilised TiO2 and UV-A LED light source (365 nm emission wavelength). Estriol levels were measured by HLPC-MS method. Four hours photocatalytic process led to decrease in estriol concentration about 54 %. The same time of photolysis (without TiO2) or adsorption (without light) had no effect to estriol concentrations.
