Appl. No.:

10/026329

Inventors:

David Vance - Houston TX
Suthan S. Suthersan - Yardley PA
Peter Palmer - Lutz FL

Assignee:

Case Logic, Inc. - Longmont CO

International Classification:

B01F 312

US Classification:

516 35, 516 33, 241 16, 241 21, 502151, 502159, 502172

Abstract:

When elemental iron is in the presence of chlorinated compounds (contaminants) a naturally occurring reaction takes place and the chlorinated compounds are reduced and form harmless compounds. The production of extremely small metal particles containing elemental iron or a mixture of elemental iron and a second metal is imperative to this method of treating contaminants and is the subject of the present invention. When the particle is made small enough a surfactant is not required for the particle to do its job. The elemental metal may be kept in an elemental state by keeping it in an oxygen-scavenging environment. This is achieved by either suspending the nanoscale metal in a carbohydrate solution or by injecting a carbohydrate solution in atomized form into the gas used to inject the metal into the subsurface soil. Additionally, the present invention is to a method of using elemental metal to reductively dehalogenate halogenated hydrocarbons, to reduce soluble metals and to treat metalloids in subsurface soil.

Abstract:

Methods of treating ground water and methods for reducing contaminants (e. g. , chlorinated compounds in contaminated ground water) to harmless compounds in the presence of an elemental metal treatment composition. Said methods comprise injecting a treatment solution comprising a colloidal suspension of elemental metal particles (e. g. , iron, a tin, a zinc, a palladium and mixtures thereof) having a nanoscale particle size and a carbohydrate in an organic liquid (e. g. , dodecane, butyl acetate and polypropylene glycol ethyl ether acetate and mixtures thereof) into the ground, proximate to the contaminated ground water.

Appl. No.:

11/139295

Inventors:

Suthan Suthersan - Yardley PA, US
David Vance - Midland TX, US
Peter Palmer - Lutz FL, US

International Classification:

C22C001/04

US Classification:

075362000

Abstract:

The invention provides methods of producing colloids of nanoscale metallic particles particularly useful in the in situ environmental remediation of chlorinated solvents. The methods include ball milling an elemental metal to form a colloid of nanoscale metallic particles having ideal size and metallurgical properties to enhance the reductive dehalogenation of halogenated hydrocarbons.
