ABSTRACT:
Oil spills on natural bodies of water are treated with amine-substituted water swelling clays. The organoclays are added to oil spills in an amount which herds oil into islands of oil separated by surfaces of water containing no oil. The clays can also be added to oil spills in an amount which produces quasisolid, buoyant organoclay/oil flocculate clumps which float in the water and which are amenable to collection from the surface of the water.
