Zero valent metal composite for catalyticaly treating contaminated water

摘要: Zero valent metal composite, manufacturing thereof, using and system including for (in-situ or ex-situ) catalytically treating contaminated water, such as sub-surface surface above-surface water vapor, or/and gaseous water. Composite includes powdered diatomite matrix incorporated with nanometer (1 - 1000 nm) sized particles of a zero (transition) (iron, cobalt, nickel, copper, zinc, palladium, platinum, gold) at least one electron transfer mediator (catalyst) from porphyrinogenic organometallic complexes (e.g., metalloporphyrins (chlorophylls, hemes, cytochromes) metallocorrins vitamin B12), optionally, vermiculite. System composite in situ ex-situ unit containing the enabling exposure thereto. Applicable to in-situ sub permeable reactive barriers (PRBs). Treatable contaminants are organics (halogenated organic compounds), inorganics (metal elements, element inorganic species, nonmetal species). non-aqueous fluids (liquids, vapors, gases), removing therefrom.
