Iron and silver nanoparticles were synthesized using a rapid, single step, and completely green biosynthetic method employing aqueous sorghum extracts as both the reducing and capping agent. Silver ions were rapidly reduced by the aqueous sorghum bran extracts, leading to the formation of highly crystalline silver nanoparticles with an average diameter of 10 nm. The diffraction peaks were indexed to the face-centered cubic (fcc) phase of silver. The absorption spectra of colloidal silver nanoparticles showed a surface plasmon resonance (SPR) peak centered at a wavelength of 390 nm. Amorphous iron nanoparticles with an average diameter of 50 nm were formed instantaneously under ambient conditions. The reactivity of iron nanoparticles was tested by the H 2O2-catalyzed degradation of bromothymol blue as a model organic contaminant. © 2010 American Chemical Society.

Patent
VeruTEK Technologies | Date: 2010-09-29

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 fruit extracts and use of these metal nanoparticles in removing contaminants from soil and groundwater and other contaminated sites.


The invention relates to a method for extracting a petroleum hydrocarbon and/or a nonaqueous phase liquid (NAPL) from a subsurface, comprising: introducing into the subsurface a surfactant and/or cosolvent to increase solubility and/or mobility of the petroleum hydrocarbon and/or NAPL and solubilize and/or desorb the petroleum hydrocarbon and/or NAPL; introducing into the subsurface a gas phase generating oxidant; allowing the gas phase generating oxidant to decompose to form a gas phase; allowing the gas phase to hydrodynamically scrub the petroleum hydrocarbon and/or NAPL from soil particles in the subsurface; inducing the petroleum hydrocarbon and/or NAPL to flow to an extraction well; extracting the NAPL from the subsurface through the extraction well. The invention also relates to a composition of an injection fluid capable of being injected into a subsurface to induce a petroleum hydrocarbon and/or a nonaqueous phase liquid (NAPL) to flow to an extraction well for extraction.
