Sažetak
Trimethoprim (2, 4-diamino-5(3’, 4’, 5’-trimetoxybenzylpyrimidine) (TMP) is an antifolate antibacterial agent used worldwide in veterinary and human medicines for the treatment of bladder infections. It is often prescribed in combination with sulfamethoxazole due to their complementary and synergistic mechanisms but may be used as a monotherapy [1]. Due to its frequent use and very low elimination rate in WWTPs, TMP has been often detected in wastewater effluents and surface waters. Previous study has shown that TMP is resistant to biodegradation and hydrolysis, while solar radiation can cause slow degradation of TMP in favourable environmental conditions and lead to a decrease in its environmental concentration [1]. In this work, the mechanism of TiO2 photocatalytic and photolytic (without photocatalyst) degradation of TMP was investigated. TiO2 photocatalyst was used in a form of nanostructured film on glass ring placed on the bottom of the reactor [2]. As a source of radiation a simulated solar radiation lamp was used both for photolytic and photocatalytic experiments. The photocatalytic mechanism has been elucidated by scavenger studies using isopropanol, ammonium oxalate and triethanolamine as hydroxyl radicals, positive holes and superoxide radicals scavengers, respectively [3]. The results showed strong inhibition of photocatalytic degradation of TMP in presence of isopropanol and triethanolamine, which means that •OH and superoxide radicals were the primary reactive radicals responsible for the degradation process. No inhibition of the photocatalytic degradation of TMP in presence of ammonium oxalate was observed.
