Abstract
This invention relates generally to a method for the extraction of organic liquid contaminates from a sample. This invention is directed to the ability of hydrophobic extraction material or ribbon tape made of a hydrophobic polymer to facilitate the extraction of liquid organic contaminates from an aqueous sample in contact with an organic non-polar solvent.
Claims10
A method for extracting organic contaminants from an aqueous sample comprising:
- (a) mixing a non-polar polymer and an organic non-polar solvent with the aqueous sample to form a mixture such that the non-polar polymer, organic non-polar solvent, and aqueous sample are in intimate contact with each other;
- (b) incubating the mixture for a sufficient period of time for the organic contaminants and the organic non-polar solvent to adhere to the non-polar polymer;
- and
- (c) then removing the non-polar polymer with the organic contaminants and the organic non-polar solvent adhering thereto from the mixture.
