Current R&D Activities
We continue to develop new classes of SAMMS™ and explore their behavior in chemical separations and preconcentration, extending our database on SAMMS™ performance. Current research interests include:
- ligand design for new chelate-SAMMS™ aimed at transition metal recovery
- sorbent stability under extreme process conditions
- integration of SAMMS™ into engineered forms to facilitate process efficiency
- integration of metal-laden sorbents into final waste forms
- regeneration methods and efficiency
- precious metal (e.g., catalyst) recovery
- actinide removal from various environments
- fundamental science issues related to the synthesis and application of SAMMS™.
In addition, we are actively involved in integrating the design concepts and synthetic methods developed as a part of this work into enhancing the sensitivity and selectivity of various analytical methods and/or sensors, thereby enabling more accurate and more reliable environmental monitoring of contaminants.
