Summary:

Waste cleanup efforts currently underway at the Savannah River Site have created a need to characterize Tc-99 in the various high activity waste matrices currently in Site inventories. The traditional method our laboratory used for analyzing Tc-99 in higher activity matrices was a solvent-solvent extraction method using Aliquat-336 in xylene, which resulted in the problematic generation of mixed waste. In an effort to eliminate the generation of mixed wastes resulting from the Aliquat 336/xylene process, a variety of different separation methodologies have been studied. Eichrom TEVA solid phase extractions using column technology have been employed in a case by case basis over the last several years. More recently, applications using Eichrom TEVA extraction discs and 3M Empore Tc extraction discs have also been explored.
