Background The oil spills from an off-shore oil rig or tanker can do tremendous damage to the esosystem in the area of the spill and expand over vast regions to affect coastlines and indigenous wildlife hundreds of miles away. Cleaning oil spills, especially in a marine environment is important and it is a challenging task. The methods currently used to clean oil in water can be divided into following categories: using booms and skimmer; using oil solidifier and dispersants; adding biological agents to speed up the oil breakdown; or in-situ burning of oil spills. However, only the skimmers were designed to recover the spill oil.1 When oil is skimmed from the surface water, much of the recovered material is water. Thus, the storage container fill-up with more water than the actual oil. For example, a weir skimmer generally recovers 70% water and 30% oil.1 To help make storage space available for actual oil, the recovered water may be decanted back into the surface water where it was collected. The collection of oil using hydrophobic/oleophilic material is preferred because it allows for the proper disposal of oil and does not cause secondary pollution. The combat global-scale water pollution arising from oil spills and industrial organic pollutant, the development of efficient absorbent material to efficiently separate and remove oil and organic pollutants from water should be of great significance in addressing the environmental issue.
