Abstract
Benzotriazoli spadaju u skupinu onečišćivala koja su prisutna u okolišu zbog svoje višestruke primjene. 1H-benzotriazol i njegovi derivati svoju primjenu pronalaze u industriji, tehnici, materijalima, lijekovima i drugim proizvodima koji se svakodnevno koriste. Kako konvencionalnim metodama pročišćavanja nije moguće u potpunosti ga ukloniti, potrebno je posegnuti za drugim metodama kojima će se osigurati njegovo uklanjanje. U ovome radu predložena je fotokatalitička oksidacija kao napredna oksidacijska metoda uklanjanja 1H-benzotriazola iz vodene otopine. Kao fotokatalizator koristi se TiO2 te TiO2/CNT, oba nanesena na podlogu staklenog mata. 1H-benzotriazol u koncentracijama 5 i 10 mg/L uklanja se u dva tipa reaktora – CPC i FPCR. U prisutnosti TiO2 mreže, BT je uklonjen iz sustava. Na temelju rezultata predložen je model fotokatalitičke oksidacije te je predstavljen njegov mehanizam razgradnje.
Abstract (english)
Benzotriazoles belong to a group of pollutants that are present in the environment due to their multiple applications. 1H-benzotriazole and its derivatives are used in industry, technology, materials, pharmaceuticals, and other products that are in everyday use. Because it is not possible to completely remove it with conventional water purification methods, other techniques need to be used to ensure its removal. In this work, photocatalytic oxidation is proposed as an advanced oxidation technique for removing 1H-benzotriazole from aqueous solution. TiO2 and TiO2/CNT are used as photocatalysts, both applied on a glass mesh substrate. Removal of 1H-benzotriazole was experimentally tested using 5 and 10 mg/L concentrations in two types of reactors – CPC and FPCR. In the presence of TiO2 mesh, BT is totally removed in both reactor setups. Based on the results, a model of photocatalytic oxidation was proposed, and its degradation mechanism was presented.
