    摘要： This invention is a novel method for bioremediation of soil and ground water based on supplying hydrogen (H2) to naturally occurring anaerobic bacteria in the soil or ground water. These organisms use the hydrogen as an electron donor to perform adventitious chemical reactions including the dehalogenation of chlorinated organic compounds. The hydrogen can be supplied from a number of sources, including; stored hydrogen, hydrogen generated above ground on site, either electrochemically or by reforming a fuel source, or by electrolysis in the soil, either using an electric current supplied from above ground or an electric current generated by the corrosion of metal particles in the ground. For the last of these cases, a novel multi-metallic particle especially useful for the generation of hydrogen, and a method for making these particles, are disclosed.

    摘要： A system for managing fluids used during electroremediation of contaminants in a porous medium, such as soil is disclosed. The system monitors the fluid gain and loss from the electrode wells and maintains optimal fluid levels in the wells on an individual basis. The system may use a sensor element for measuring the metal ion content of the electrode well fluid. A method for using the fluid management system is also disclosed.

    摘要： The present invention provides a formulation for forming an electronically conducting polymer. The formulation contains an electron acceptor comprising a dopant anion and a metal cation selected from Ag+, Fe3+, Cu2+ or combinations thereof. The preferred electron acceptor is a silver salt, preferably selected from AgNO3, AgClO4 and AgNO2. The formulation also contains between 2 and 100 moles of a polymerizable component per mole of the electron acceptor, the polymerizable component being selected from pyrrole, aniline, their oligomers, or combinations thereof. In addition, the formulation includes an aqueous solvent selected from acetonitrile, acetone, and combinations thereof, the aqueous solvent having up to 30 volume percent water.
