Sorption studies on the removal of cesium, strontium, and technetium from supernatants from underground storage tanks at ORNL
- Oak Ridge National Lab., TN (United States); and others
Bench-scale batch equilibration tests have been conducted with supernatants from several tanks at the Melton Valley Storage Tank (MVST) Facility at Oak Ridge National Laboratory (ORNL) to evaluate and compare the effectiveness of selected ion exchangers for removing cesium, strontium, and technetium. The MVST supernatants are similar in composition to some of the supernatants stored in the Hanford tanks, and these data should prove useful in the overall evaluation of the ion exchangers for applications to Hanford and other U.S. Department of Energy sites. Eight sorbents were evaluated for cesium removal, ten for strontium removal, and six for technetium removal. Kinetic and isotherm data, as well as data showing the effects of the concentrations of cesium and potassium on the removal of cesium from the supernatants, will be presented. Kinetic and isotherm data for the removal of strontium and technetium will be given. A test to determine the solubility of strontium in one of the supernatants will be described.
