The effect of Crude oil spillage is felt in every aspect of human civilization. Its treatment procedure still remains a challenge to the developing world due to the very high cost of implementation of the existing techniques. In this study, Pineapple Crown which is an eco-friendly, Cheap and easily available agro-waste was chemically modified (APA) for the treatment of oil spillage in aqueous medium and its performance compared with the raw sample (RPA). The characterization of the sample using FT-IR, revealed the suitability of the sorbents for acetylation and sorption process, giving the extent of acetylation as 1.68. Date from the study of the effect of time, dosage and temperature was employed for the study of the kinetic models which then suggested that, sorption process occurs through both pore and surface diffusion mechanisms, the R2 value generated for RPA was best fitted to Pseudo first order while APA was best fitted to Pseudo second order. The Isotherm study done generated R2 values best fitted to Temkin with values of 1.000 and 0.999 for RPA and APA respectively thus depicting that the sorption process were both multilayer sorption and endothermic in nature. The thermodynamic study confirmed the physisorption and chemisorption’s nature of RPA (18.0KJ/mol-1) and APA (30.7 KJ/mol-1) in the sorption process as well as the endothermic nature as seen the values of enthalpy. The negative value seen in Gibb’s energy correlates to the spontaneous nature of the sorption process. The results presented and discussed in this study conclusively projects the acetylated pineapple crown as preferred sorbent material in the treatment of crude oil spillage.
