International Classification:

A62D 3/00

C02F 3/00

US Classification:

4352625, 435262, 435281, 2082621, 2082625, 40512845, 4051285, 210601, 210610, 210611, 210613

Abstract:

The present invention provides a method and gaseous composition for the in situ bioremediation of soil and groundwater contaminated with organic compounds, including halogenated hydrocarbons. The gaseous composition, which readily permeates a subsurface region, comprises hydrogen (H) and one or more volatile phosphates, such as triethylphosphate (TEP) and tributylphosphate (TBP). The volatile phosphates serve as nutrients that stimulate the growth and activity of indigenous microbes that are capable of degrading the contaminants. The addition of hydrogen facilitates the direct reductive dehalogenation of highly halogenated contaminants. The gaseous composition may optionally contain one or more of a volatile alkane and nitrous oxide as additional supports for microbial growth, and carbon dioxide to lower the pH of remediation sites that are highly alkaline.

International Classification:

G01N 3348

US Classification:

436165

Abstract:

A device is provided for both collecting and testing a fluid specimen. The device includes a specimen container having a collection chamber, an isolation chamber and a test chamber. The collection chamber is in fluid communication with the isolation chamber and sealed from the test chamber. The isolation chamber is also sealed from the test chamber. The fluid specimen is collected in the collection chamber and an aliquot is isolated in the isolation chamber. A fluid releasing element is provided to release fluid from the isolation chamber and establish a flow path to the test chamber while sealing the isolation chamber from the collection chamber. In accordance with another aspect of the present invention, the specimen container may include a tamper evident lid which provides an identification of whether or not the container has been opened which may indicate that the contents of the container have been compromised.

International Classification:

C01B 3/24

Abstract:

A method for producing hydrogen and carbon from hydrocarbons in a reaction chamber is provided. The method includes introducing a hydrocarbon into a chamber such that the hydrocarbon rotates in a first direction. The method includes generating a direct current (DC)-based plasma from a portion of the hydrocarbon, wherein the hydrocarbon is heated to a temperature greater than 1,000 C. at least in part by the DC-based plasma. The method includes rotating the DC-based plasma in a second direction that is different from the first direction. The method includes converting the hydrocarbon into elemental constituents of the hydrocarbon comprising carbon solid and hydrogen gas. The method includes separating the carbon solid from the hydrogen gas to provide a solid part and a gas part.
