Decontamination of Soil Contaminated with Aroclor 1260 Using a Solvent Extraction Process and γ-Ray Radiolysis
-
Abstract
Radiolytic dechlorination of halogenated organic compounds in soil has proved to require large γ-ray doses. In collaboration with INEEL, the University of Missouri investigated a new approach for the dechlorination of polychlorinated biphenyls in soil. The chemistry of an existing solvent extraction-floatation process was modified and then used to desorb Aroclor 1260 from a soil matrix. The chemistry of the floatation process was tailored to allow radiolytic dechlorination of the Aroclor 1260 once it was desorbed into the floatant. For the process, Soltrol 130 and an alcohol solution were used as the solvent-extractant. The efficiency of using gamma radiolysis to dechlorinate the Aroclor 1260-floatant solution was investigated using a Co-60 source located at the University's Research Reactor. When Aroclor 1260 was desorbed from the soil surface with the floatation process and irradiated, the dose constant (efficiency) was 40 times greater than when soil was irradiated alone.
