Pollution of marine ecosystem and land through the release of liquid petroleum hydrocarbon by accidental spillage remains one of the most significant issues to environmental researchers. In this study, chitosan from land snail shell, a biodegradable agricultural waste and epoxidized natural rubber (ENR) were synthesized. The two were compounded and used in the study of sorption of petrol and crude oil. The equilibrium isotherm data of epoxidized natural rubber-chitosan (ENR-C 2h) was also analyzed using the Langmuir, Temkin isotherms. The regression coefficients (R2) of Langmuir isotherm model was observed to be the highest in the experimental data. The maximum monolayer coverage (Qm) determined from Langmuir isotherm model was 0.8425 and the separator factor was 0.3417, thus confirming a favourable sorption. The sorbent used in this study showed a good sorption capacity while the ENR-C 2h was found to be a potential treatment for oil spills. Â
