ABSTRACT:
The invention relates to compositions and methods for removing oil from water surfaces. The composition comprises a fine grained particulate material, such as expanded perlite or vermiculite, or sand, coated with an oleophilic/hydrophobic layer comprising sulfur, a metallic sulfate, an alkali metal nitrate, and burned hydrocarbon oil. The invention is particularly applicable to the treatment of oil spills on the surfaces of open bodies of water, such as lakes, rivers and oceans. The invention also relates to methods for preparing the oil removal composition, and for stripping and recycling the compositions after use.
