Organic solvents may appear in wastewaters and other industrial waste streams containing dyes, therefore, their photodegradation catalyzed by TiO2 should be investigated. Solvent effect on photodegradation of CI Reactive Orange 16 has been studied using simulated solar light and P-25 TiO2. Methyl, ethyl and isopropyl alcohol as well as acetone were used as solvents. Photodegradation reaction was faster in methyl than in ethyl alcohol while in water was the slowest. RO16 photodegradation efficiency and reaction rate decreased in the presence of small concentration of ethanol. Higher photodegradation efficiency was observed for higher ethanol concentration. For acetone, photodegradation decreased as concentration of acetone increased. It seems that protic solvents at higher concentrations promote reaction, while at low concentrations slow down reaction. Aprotic solvents slow down reaction.
U radu je ispitivan uticaj organskih rastvarača na fotodegradaciju sintetske boje (C.I. Reactive Orange 16) u vodi u prisustvu TiO2 kao katalizatora upotrebom simulirane sunčeve svetlosti. Kao rastvarači korišćeni su metil-alkohol, etil-alkohol, izopropil-alkohol i aceton. Reakcije su izvođene kako u čistim rastvaračima tako i pri različitim odnosima rastvarač/voda. Fotodegradacija boje je praćena UV/Vis spektrofotometrijom.
