Abstract (croatian)

Problematika zaštita voda već dugo je jedna od najvažnijih tema zaštite okoliša. Kada se govori o mikroonečišćenjima u vodi jedan od najvećih problema su farmaceutici. Utvrđivanje njihove prisutnosti nije samo posljedica razvoja analitičkih metoda nego i masovne uporabe farmaceutika te njihove sve veće koncentracije u okolišu. U ovom radu su pripremljeni i karakterizirani napredni fotokatalizaori dobiveni kroz dva različita postupka imobilizacije titanijeva dioksida (TiO2) na nosač sol-gel... More metodom. Imobilizacija je provedena klasičnim i mikrovalnim sušenjem te su katalizatori karakterizirani pretražnom elektronskom mikroskopijom (SEM), energijsko disperzivnom rendgenskom spektroskopijom (EDS) i rendgenskom difrakcijskom analizom (XRD). Aktivnost
fotokatalizatora je ispitana kroz sposobnost fotokatalitičke razgradnjom salicilne kiseline (SA) u pilot reaktoru, čija je razgradnja praćena UV-ViS spektrometrom. Less

Abstract (english)

The issue of water protection has long been one of the most important environmental issues. When it comes to the micropollutants, one of the greatest problems is pharmaceuticals. Their detection is not only a consequence of the development of analytical methods but also of the massive use of pharmaceuticals and their increasing concentration in the environment. In this paper, advanced photocatalysts were prepared and characterized by two different processes of titanium dioxide... More immobilization (TiO2) on the support through sol-gel method. Immobilization was performed by the classical and microwave-assisted drying, and the catalysts were characterized by scanning electron microscopy (SEM), energy dispersion X-ray spectrometry (EDS) and X-ray diffraction analysis (XRD). The photocatalyst activity was tested through the photocatalytic degradation of salicylic acid (SA) in the pilot reactor, monitoring the degradation by the UV-vis spectrometry. Less
