Abstract
The photocatalytic degradation of the synthetic textile dye CI Basic Yellow 28 (BY28) in water, using a recently synthesized P160 TiO2-based catalyst, under Osram ultra-vitalux® lamp (300 W) light, was studied. The effects of the operational parameters, such as initial concentration of catalyst, initial dye concentration and pH, were studied. The salt effect (NaCl, Na2CO3, Na2SO4 and NaNO3) was also investigated. It was found that the optimal concentration of catalyst is 2.0 g L-1. A pseudo first-order kinetic model was illustrated using the Langmuir-Hinshelwood mechanism and the adsorption equilibrium constant and the rate constant of the surface reaction were calculated (KBY = 6.126 L mg-1 and kC = 0.272 mg L-1 min-1, respectively). The photodegradation rate was higher in weak acidic than in high acidic and alkaline conditions. The presence of CO32- ions increased the photodegradation rate while Cl-, SO42- and NO3- decreased the reaction rate. The rate of photodegradation of BY28 was... measured using UV-Vis spectroscopy.

U radu je proučavana fotokatalitička degradacija sintetske tekstilne boje CI Basic Yellow 28 u vodi, koristeći nedavno sintetisani katalizator na bazi P160 TiO2, i Osram ultra-vitalux® lampu (300 W). Proučavan je uticaj različitih parametara na reakciju, kao što su: početna koncentracija katalizatora, početna koncentracija boje, prisustvo soli (NaCl, Na2CO3, Na2SO4 i NaNO3) i pH. Utvrđeno je da je optimalna koncentracija katalizatora 2,0 g L-1. Koristeći Langmuir-Hinshelwood mehanizam određene su ravnotežna adsorpciona konstanta i konstanta brzine površinske reakcije (KBY = 6,126 L mg-1 i kC = 0,272 mg L-1 min-1). Brzina reakcije je veća u slabo kiseloj sredini u poređenju sa jako kiselom ili baznom sredinom. Prisustvo CO32- povećava brzinu reakcije fotodegradacije dok je Cl-, SO 2- i NO3-smanjuju.
