- Abstract
This paper presents the decolorization of p-Dimethylaminobenzalrhodanine using titanium dioxide nano-particles under photocatalytic process at various buffer media under air atmosphere. Several effective agents including nano-photocatalyst loading, illumination time, pH of medium and initial dye concentrations have been subjected to be estimated. Furthermore, kinetic investigations of photocatalytic process fitted the pseudo-first-order kinetic for dye decolorization at all considered buffer media. Then Langmuir-Hinshelwood model was applied for evaluation of photodecolorization rate constant (kr) and adsorption constant KA for all media. Spectrophotometric monitoring showed that the titled dye is nearly decolorized completely after 9-15 h and 3.5 h at buffer pHs of 9-12 and pH of 13 under high pressure irradiation respectively.
