Dr.
Larsen received his B.S. degree from Dana College and his Ph.D.
from Northwestern University. He joined the UM-St. Louis faculty
in 1964, after one year as a research associate at Washington
University.

Research
Interests
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.
