20100185039 | METHOD FOR EXTRACTION AND SURFACTANT ENHANCED SUBSURFACE CONTAMINANT RECOVERY - Methods and compositions for removing contaminants from soil and groundwater by extracting the contaminants and assisting the extraction by provision of an oxidant introduced prior to or simultaneously with a surfactant into the subsurface. Extractable contaminant can be extracted from the subsurface. The amount and/or distribution of contaminant in the subsurface can be characterized. The extracting of contaminant and the introducing of oxidant and surfactant can be coordinated to reduce contaminant to a target amount. A portion of the contaminant can be oxidizable. | 07-22-2010 |
20100200501 | GREEN SYNTHESIS OF NANOMETALS USING PLANT EXTRACTS AND USE THEREOF - The present invention relates to methods of making and using and compositions of metal nanoparticles formed by green chemistry synthetic techniques. For example, the present invention relates to metal nanoparticles formed with solutions of plant extracts and use of these metal nanoparticles in removing contaminants from soil and groundwater and other contaminated sites. In some embodiments, the invention comprises methods of making and using compositions of metal nanoparticles formed using green chemistry techniques. | 08-12-2010 |
20100232883 | POLYMER COATED NANOPARTICLE ACTIVATION OF OXIDANTS FOR REMEDIATION AND METHODS OF USE THEREOF - Methods of decreasing the amount of one or more contaminants in contaminated soil comprise introducing polymer-coated nanoparticles into the contaminated soil, optionally with other reagents. The polymer-coated nanoparticles exhibit an enhanced ability to migrate through the soil and provide greater control of the rate of activation of other chemicals, such as oxidants, in the contaminated soil. | 09-16-2010 |
