Studies on UV/NaOCl/TiO2/Sep photocatalysed degradation of Reactive Red 195.
J Hazard Mater. 2010 Feb 15; 174(1-3):864-71.JH

Abstract

The photocatalytic degradation of Reactive Red 195 (RR195) has been investigated in aqueous suspensions by using ultraviolet (UV), sodium hypochlorite (NaOCl) and TiO(2)/Sep nanoparticles together. To get the TiO(2)/Sep nanoparticle, the nanocrystalline TiO(2) anatase phase on sepiolite was obtained using a sufficient thermal treatment by gradually increasing the temperature from 300, 400 and 500 degrees C for 3h. Then, TiO(2)/Sep materials were characterized using different spectral and technical structural analyses with scanning electron microscopy (SEM) and X-ray diffraction (XRD). The influence of pH, catalyst amount, oxidant and initial dye concentration was investigated in all the experiments. Maximum colour and chemical oxygen demand (COD) removal were 99.9% and 78% respectively, at a dye concentration of 250 mg L(-1), NaOCl dosage of 50.37 mM, 0.1 g L(-1) weight of TiO(2)/Sep and pH of 5.45 in 3h. In addition, the pseudo-first order model was applied and r(2) values were noted from 0.92 to 0.99.
