Abiotic transformation of carbon tetrachloride at mineral surfaces. Final report, September 1990-September 1993

OSTI ID:5047890
The report addresses the ability of natural mineral surfaces to abiotically transform halogenated organic compounds in subsurface environments. The research focuses on carbon tetrachloride (CC14) as the halogenated organic and biotite, vermiculite, and pyrite as the mineral surfaces. The CCl4 transformation rates and products were quantified under different environmental conditions. The disappearance of CCl4 was significantly faster in the presence of mineral surfaces than in homogeneous solution. In systems containing the sheet silicates and HS-, the rate of reaction was dependent on the temperature, hydrogen sulfide ion concentration, surface concentration, and Fe(II) content in the minerals.
