I. Prabha, S. Lathasree

Abstract :

 The present work involved synthesis, characterization of ZnO nanoparticles for the photodegradation of textile effluents in wastewater. ZnO nanoparticle was synthesized by sol–gel process followed by calcination at 500°C and XRD, SEM and BET surface area methods were used to analyze its crystallite size, particle size and surface area. The crystallite size of ZnO nanoparticles was found to be comprised of 25–35 nm and the particle size was confirmed as 30 ± 5 nm with the large agglomerates with individual nanoparticles are heterogeneous and spherical in shape. The photocatalytic activity of ZnO nanoparticle was evaluated using reactive red 198 as a model compound. Under optimum conditions, nano ZnO has undergone complete degradation within 90 minutes of degradation time and it has showed higher degradation rate under the same condition.
