Abstract
A method and apparatus for removing organic contaminants from an aqueous phase in which the contaminant is solubilized. In the method the aqueous phase is passed through a fluid-pervious filtration media which has been infused with an absorbtion composition comprising a homogeneous thermal reaction product of an oil component selected from the group consisting of glycerides, fatty acids, alkenes, and alkynes, and a methacrylate or acrylate polymer component. The absorbtion composition is cured in situ at the filter. The contaminant is immobilized at the media, and the purified filtrate having passed through the filtration media is collected as the product. The said oil component comprises at least 95% by weight of the combined oil and polymer components.
