Adsorptive removal of methyl orange dye from aqueous solution using populous leaves: Insights from kinetics, thermodynamics and computational studies

The present investigation reports an effective adsorption of methyl orange dye using the leaves of populous tree in five different forms. The physicochemical properties of all adsorbents were characterized using instrumental analyses such as Fourier transform infrared spectroscopy (FTIR), powder x-r...
