Dr. Larsen's research interests are in environmental chemistry, especially in the development of novel methods to treat hazardous waste including "mixed" (radioactive) waste. Research areas of interest include the preparation of activated char from coal and the regeneration of spent activated carbon by special gasification techniques. Gasification methods to treat mixed wastes containing oils, PCB's, dioxins, heavy metals, and radionuclids are also of interest. The gasification methods are applied to the treatment of effluent streams, sludges, and contaminated soils.
