Filed:

Oct 2, 2001

Appl. No.:

09/972296

Debra R. Reinhart - Maitland FL
Christian Clausen - Chuluota FL
Cherie L. Geiger - Geneva FL
Jacqueline Quinn - Titusville FL
Kathleen Brooks - Orlando FL

Assignee:

The United States of America as represented by the Administrator of the National Aeronautics Space Administration - Washington DC

International Classification:

B01F 1700

US Classification:

516 22, 588248, 252181, 252178

Abstract:

A zero-valent metal emulsion is used to dehalogenate solvents, such as pooled dense non-aqueous phase liquids (DNAPLs), including trichloroethylene (TCE). The zero-valent metal emulsion contains zero-valent metal particles, a surfactant, oil and water. The preferred zero-valent metal particles are nanoscale and microscale zero-valent iron particles.

US Classification:

516 20, 1663051, 166310, 2101981, 252181, 4051285, 40512925

Abstract:

A zero-valent metal emulsion containing zero-valent metal particles is used to remediate contaminated natural resources, such as groundwater and soil. In a preferred embodiment, the zero-valent metal emulsion removes heavy metals, such as lead (Pb), from contaminated natural resources. In another preferred embodiment, the zero-valent metal emulsion is a bimetallic emulsion containing zero-valent metal particles doped with a catalytic metal to remediate halogenated aromatic compounds, such as polychlorinated biphenyls (PCBs), from natural resources.

International Classification:

G01N 714
G01N 122

US Classification:

7386473

Abstract:

Gas flux rate from a surface is measured using an elongated tubular housing having a lower open end and an upper open end with a support positioned within the housing a predetermined distance from the lower open end. A gas sampling wand extends into the housing from the upper open end and is supported on the support. The wand has a lower open end at the support generally co-planar with the lower open end of the housing. An air baffle is coupled to the upper open end of the housing for reducing velocity and pressure fluctuations of atmospheric air entering the housing from the upper end. A detector is coupled to the wand for measuring the concentration of selected gases within the housing. A funnel-shaped hood circumscribes the lower open end of the wand and increases the sample collection area of the wand. An air pump is coupled to the wand for drawing air and gases into the wand from the area adjacent the lower open end of the housing.

International Classification:

C02F 170
A61L 202

US Classification:

422128

Abstract:

A method for increasing the effectiveness of a permeable treatment wall is described. The method includes the introduction of ultrasonic radiation in or near the wall. A permeable treatment wall is also described which has an ultrasonic radiation generating transducer in or near the wall. Permeable treatment walls are described as having either a well vertically extending into the wall, or a rod vertically extending into the treatment wall. Additionally, a method for adapting a permeable treatment wall to allow for the introduction of ultrasonic radiation in or near the wall is described.
