Technetium-99 (99Tc) is present at several U.S. Department of Energy (DOE) facilities, including the Hanford, Oak Ridge, Paducah, Portsmouth, and Savannah River sites. Due to its mobility, persistence, and toxicity in the environment, developing means to immobilize and/or remove technetium from the environment is currently a top priority for DOE. However, there are currently very few approaches that effectively manage the risks of technetium to human health and the environment. The objective of this study is to evaluate novel synthetic materials that could enable direct removal of technetium from groundwater. The following report
•assesses the viability of existing methodologies for synthesis of tin (II) apatite for in situ formation and remediation of 99Tc within the subsurface environment
•discusses the development of alternative methodologies for production of tin (II) apatite
•evaluates nanoporous tin phosphate materials for removal of technetium from groundwater.
