Degradation of methylene blue using graphene oxide and aluminium oxide nanoparticles and nanocomposites

Abstract Methylene blue dye was degraded by using graphene oxide and aluminium oxide nanoparticles and with their nanocomposites. Graphene oxide and aluminium nanoparticles were synthesized by using modified Hummers method, sol-gel method respectively. Degradation of methylene blue of different concentrations was determined using graphene oxide and aluminium oxide nanoparticles and the absorbance value was evaluated using UV spectrometer Evaluation of methylene blue degradation and their characterization are analysed by using FTIR & SEM.The maximum degradation achieved by Graphene oxide nanoparticles is 99.6% andthe maximum degradation achieved by Aluminium oxide nanoparticles is 95.9%. Comparing to Graphene Oxide and Alumina, Nano composites have the higher degradation efficiency of 99.8% at the initial concentration. The degradation of Methylene blue was examined using varied concentrations of dye, nanoparticles & nanocomposites. The degradation rate rises as the concentration of nanoparticles rises, according to the findings. Graphene oxide and Nanocomposites were shown to be more efficient at degrading methylene blue than Aluminium oxide, with a maximum efficiency of 99.9%. Nanocomposites ˃ Graphene oxide ˃Aluminium oxideGraphene oxide nanoparticles and aluminium oxide nanoparticles can be used for the removal of methylene blue dyes which poses severe threat to environment
