Evaluation of Improved Techniques for the Removal of Fission Products fromProcess Wastewater and Groundwater: FY 1998 and 1999 Status

摘要

The primary goal of this program is to test new materials for their capacity toremove fission products, namely (sup 90)Sr and (sup 137)Cs, from near-neutral-pH wastewater and groundwater containing competing cations. In the past several years, many materials have been tested for their ability to meet these criteria. Testing has encompassed physical and chemical characterization of these materials; batch and column testing to quantify their uptake of strontium and cesium; and testing of the select materials on actual waste against the baseline sorbent, chabazite zeolite. Results and conclusions have been summarized yearly in status reports. This report summarizes the information obtained during fiscal years (FY) 1998 and 1999.
