Oil spills exhibit a major threat to the marine and coastal environment. They are mainly caused by accidental episodes of super oil tankers, the food and chemical industries, oil drilling, as well as natural events. Discharging wastewater from these processes into the environment has become a significant concern for current oil production techniques such as fracking. Therefore, the resulting environmental disaster is essential to the use of cost-effective cleaning systems. Different materials have been used for oil remediation such as adsorbents, solidifiers, dispersants and booms. The most important requirements for surface water management include the availability of rapid and efficient specific adsorbents. A literature overview indicates that a variety of materials have been examined extensively for this purpose and can be categorized into (a) inorganic mineral sorbents, (b) synthetic organic sorbents, and (c) natural organic sorbents. Conventional natural materials such as sawdust, zeolite and wool fiber have been extensively used for oil removal due to their porous structures and high surface area. However, the major drawback of these materials is that water and oil cannot be separately absorbed, and as such their adsorption efficiency is poor. Thus, the present study examines the absorption capacity of different types of synthetic organic materials and their potential for oil spills clean up
