Oil spill became a significant problem of concern due to its serious impact on the natural marine ecosystem. Therefore, the control of oil spill pollution in the marine environment in a sustainable manner is the main focus of this study. The use of natural sorbents is promising and deserves attention, because they are very efficient, available, eco-friendly and low cost. Sorbents are insoluble materials used to recover liquids through the mechanism of absorption or adsorption or both. In this study, peat moss, sunflower seed cake, polypropylene and clay were used for crude oil sorption. Also, in this study four specific pollutants (most persistent organic pollutants in accidental oil spills) were used: C Marine oil, Russian Export Blend Crude Oil, diesel and gasoline. The results presented and discussed in this work point out that the tested sunflower seed cake may be considered an excellent potential sorbent for oil. This sorbent is a by-product of oil refining (provided by squeezing oil from them), a biodegradable sorbent, with average sorption properties and good buoyancy. Also the results indicate that peat moss has a higher oil sorption capacity compared to the others. [ABSTRACT FROM AUTHOR] |
