Abstract
U ovom radu ispitana je fotolitička i fotokatalička razgradnja farmaceutika cefdinira, antibiotika širokog spektra djelovanja, jednog od najčešće korištenog za liječenje infekcija dišnog sustava. Fotolitička i fotokatalitička razgradnja ispitana je uz primjenu UV- svjetiljki uz tanki film TiO2 kao fotokatalizator. Ispitan je utjecaj pH-vrijednosti na brzinu fotolitičke i fotokatalitičke razgradnje. Istraživanja su provedena s ultračistom vodom i sintetskom komunalnom otpadnom vodom. Razgradnja je praćena tekućinskom kromatografijom visoke djelotvornosti vezanom s detektorom s nizom dioda. Rezultati su pokazali da djelovanjem UV-zračenja dolazi do razgradnje cefdinira, odnosno smanjenja njegove koncentracije tijekom vremena. Smanjenje koncentracije je bitno ubrzano dodatkom korištenog katalizatora, dok se razgradnja cefdinira različito ponašala s obzirom na valne duljine zračenja. Međutim, rezultati kinetike su dokazali da sve reakcije slijede reakciju prvog reda.
Abstract (english)
The photolytic and photocatalytic degradation of pharmaceutic cefdinir, an antibiotic of a wide spectrum of action and one of the most commonly used to treat respiratory infections, is tested and described in this essay. Photolytic and photocalytic degradation was tested using UV lamps with thin film of TiO2 as a photocatalyst. The influence of pH on speed of photolytic and photocatalytic degradation was also tested. The research was conducted with ultra clean water and synthetic municipal wastewater. The degradation was monitored by high performance liquid chromatography coupled with a diode array detector. The results showed that cefdinir degradation occurs by the action of UV radiation. Reduction of concentration was significantly accelerated by adding the catalyst, while the cefdinir degradation behaved differently depending on the wavelengths of radiation. However, kinetic results showed that all reactions follow a first order reaction.
