Project Summary (1995-2000)

This project specifically determines when chromium particles or hybrid metal/soot particles form under thermal oxidation conditions, their size and chemical characteristics, and subsequent health hazards that are associated with their presence in a treatment system effluent or waste. The project includes, in its later state, a fundamental study of two promising technologies for the treatment of volatile chlorinated hydrocarbons that may be evolved during soil decontamination. An experiment in a stagnation flow is being conducted in order to determine the impact of varying vapor composition on the effectiveness of a catalyst and a ceramic bed.
