Abstract:

Nanotechnology is gaining popularity due to its multi applications in various applied fields like textile industry. The green synthesis of metal or metal oxide nanoparticles is an eco-friendly, stable, simple, rapid and cost-effective approach. In the current study, fruit peels extract of Punica granatum (Pomegranate) were utilized for the synthesis of zinc oxide nanoparticles (ZnO-NPs). The synthesized zinc oxide nanoparticles were characterized by different spectro-analytical techniques like SEM, XRD, FTIR etc. The particle size of ZnO nanoparticles was found to be 39-40 nm. Optimized conditions for the preparation of zinc oxide nanoparticles were found to be temperature 80 °C, pH 9, reactant ratio 1:5 and 80 minutes contact time. The ZnO nanoparticles were employed for the remediation of Acid Blue A dye following the optimization of experimental parameters like dye concentration (Acid Blue A), ZnO nanoparticles concentration, pH, dose of H2O2 and temperature. The Acid Blue A dye was 87% decolorized at 0.04 % dye concentration, 3 mg ZnO nanoparticles concentration, pH 6, 0.4 M H2O2 at 40 °C. Dye treated sample was subjected to chemical oxygen demand (COD) and total organic carbon (TOC) measurements. The COD and TOC values were found to be 90 % and 89.34 %, respectively. It can be concluded that synthesized ZnO nanoparticles successively degraded our targeted dye. These synthesized ZnO nanoparticles could be applied for the detoxification of other toxic dyes as well.
