Abstract

Environmental pollution caused by oil spills poses significant risks to both human health and ecosystems, particularly in regions like Nigeria’s Niger Delta, where oil spills are frequent. Conventional methods for oil spill cleanup have limitations, which has prompted research into alternative, more effective techniques. This study investigates the use of agro-based materials, specifically plantain and banana species, combined with clay soil as adsorbents for oil removal in freshwater and saltwater environments contaminated with Premium Motor Spirit (PMS) and Automotive Gas Oil (AGO). The adsorbents were prepared using a calcination method and their effectiveness in adsorbing pollutants such as ammonia (NH₃), potassium (K), sulfur (S), copper (Cu), manganese (Mn), and phosphorus (P) was evaluated over time. Various kinetic models, including Langmuir, Freundlich, and Temkin, were applied to analyze the adsorption behavior. The results indicate that the adsorbents exhibited substantial removal of contaminants, with the efficiency varying depending on the adsorbent type, contaminant, and environmental conditions. The adsorption process showed a clear trend of initial rapid adsorption, followed by saturation and reversibility in some cases. These findings suggest that agro-based adsorbents could offer a cost-effective and sustainable solution for mitigating oil pollution in water bodies.
