Patents by Inventor George A. Ivey

George A. Ivey has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Air, soil and ground water remediation compositions and methods
    Patent number: 6447207
    Abstract: A remediation composition for cleaning a soil mass and ground water contaminated with an organic contaminant and for reducing emanation of foul air from contaminated sites. The composition comprises an aqueous carrier, TRITON X-100 as a first surfactant, and a second surfactant which is selected from a group of surfactants consisting of TRITON X-155 and TRITON X-190. In presence of certain hydrocarbon, a total contaminant-emulsifying capacity of the remediation composition is greater than a sum of the contaminant-emulsifying capacities of the first and second surfactants. In another aspect of the present invention, surfactants TRITON X-15, TRITON X-35 and TRITON X-45 are used in association with TRITON X-100 such that their miscibilities with an aqueous carrier in the presence of TRITON X-100 is greater than their solubilities with the aqueous carrier alone.
