A composition includes an aqueous solution including at least one fluorinated organic compound; and a reaction product of a source of iron(II) and a source of sulfite in the presence of water and molecular hydrogen. A method of making a catalyst includes reacting a source of iron(II) and a source of sulfite in the presence of water and molecular hydrogen. The water may include less than or equal to 1 weight percent dissolved molecular oxygen. The catalyst may be used for degrading fluorinated organic chemicals in aqueous media.

Synthesis and immobilization of a ferrous sulfite catalyst and method of degrading fluorinated organic chemicals in aqueous media

A method and apparatus for treating residuals or waste streams from a plant, such as a drinking water treatment plant. The method includes the steps of obtaining plant residuals or waste streams from a water treatment plant and irradiating the plant residuals or waste streams using microwave radiation from a microwave source. The method also includes the step of drying the plant residuals or waste streams to a predetermined moisture, volume, or weight content reduction and disposing of the same.

Microwave drying apparatus for the minimization of drinking water plant residuals

A process and catalyst for the in situ generation of hydrogen via the microwave irradiation of a ruthenium chitosan composite catalyst has enabled the convenient reduction of nitro compounds in aqueous medium.

Ruthenium on chitosan (ChRu): concerted catalysis for water splitting and reduction

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.

Green synthesis of nanometals using plant extracts and 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.
