Abstract: This study helps to understand the adsorption of Malachite Green (MG) on α-MnO2 nanoparticles which was green synthesized using sugarcane juice. Different parameters including pH of solution, dosage of adsorbent, concentration of pollutant and time for adsorption process was studied to conclude the efficacy of the process using the adsorbent. The isotherm and kinetics for adsorption of MG concluded that Langmiur isotherm and pseudo second order kinetic model yields the best fit. The maximum monolayer sorption according to Langmiur was found to be 300.03 mg/g. So, α-MnO2 nanoparticles prove to be a cost effective, environment friendly and easily available 3D adsorbent.
