Abstract: In this study, stable metal oxide nanoparticles were synthesized by using Aloe barbadensis leaf extracts. The present study tracing of an object is a green synthesis of nanoparticles by the interaction of leaf extract and metal oxide salt and its azo dye (Congo red) degradation efficiency. The characterization was performed by XRD, SEM, FTIR, UV spectroscopy. The XRD analysis showed that average particle size was between 5-30nm by Scherrer equation. The effect of variables like concentration, time, PH, adsorbent dosage also examined in this present study on % degradation of dye. The nanoparticles removed about 70-8% of Congo red dye from solution at optimum condition of reaction parameters. The kinetics of pseudo second order was followed by adsorption process by MO-NPs.
