ABSTRACT:
A process for removing an organic contaminant from a body of water containing an undesired liquid organic contaminant such as an oil or an organic solvent, that includes the steps of depositing a particulate, water insoluble calcium, magnesium, or aluminum salt of an organic acid having between 10 and 22 carbon atoms in the water, maintaining the particulate material in contact with the contaminant for a time effective for the contaminant to become bound to the particulate material. The particulate material and the contaminant are then removed from the water. The preferred insoluble salt is calcium stearate.
