Photodegration of Anionic Dyes Using Polyazomethine/Titanium di-Oxide and Polyazomethine/ Zinc Oxide Nanocomposites

Abstract:
In this present research work, Poly(azomethine), ZnO, TiO2, poly(azomethine)/TiO2 and poly(azomethine)/ZnOnanocomposites were synthesized. Prepared nanocompositewas characterized by FourierTransform-Infrared spectroscopy, UV-Visiblespectroscopy, PowderX-raydiffraction, band gap, EDAX and SEM. The Photocatalytic activity of the samples was evaluated for the degradation of MethylorangeandAlizarin red S under natural sunlight. The effects of dye concentration were studies for the decolorization of MethylorangeandAlizarin red S. The degradationefficiency,reactionkinetics and isotherm studies revealed that the Polyazomethine /ZnO(PNZ) and poly(azomethine)/TiO2(PNT) nano-composites have shown excellent photocatalytic activity than PAZ, ZnO and TiO2.At optimum dye concentrations of 10ppm Methyl orange and Alizarin Red S shows maximum degradation efficiency was 87% and 86% usingPNZ and PNT nanocomposites asaphotocatalysts at 5 h contact time. FT-IR, UV-Visible spectroscopy, SEM and EDAX were used to describe the samples after the photocatalytic investigation. To examine the effect of decolorisation of dyes using synthesized photocatalysts Pseudo first order kinetic, pseudosecond order model, Langmuir, Freundlichisothermsstudieswere carriedout and also followed by intra-particle diffusion model, whereas diffusion is not only the rate-controlling step. The results show that the degradation capacity decreases with an increase in solution temperature from303 K to 333 K. The thermodynamics parameters were evaluated.
