Abstract
In this study, mango leaves, an agricultural biomass waste, were assessed as adsorbent biomass for oil removal from seawater by adsorption. Mango leaves were investigated by wettability and Fourier-transform infrared spectroscopy analysis. In the exothermic system, the maximum oil sorption capacity of biomass reached (6.66 g/g) at 3 min and 0.15 g dose of biomass. The oil sorp-tion outcomes were studied by kinetic and isotherm studies, and the outcomes showed that the oil uptake was fitted with the pseudo-second-order kinetic (R2 = 0.9921; chi 2 = 0.0347) and Redlich- Peterson (R2 = 0.9982; chi 2 = 0.0134) models. Also, the economic recycling of biomass was evalu-ated. The effective oil-adsorbing ability of mango leaves made them good adsorbent material for oil spill removal and for being used in an oil/water purification system.
