Heavy Metal/Radionuclide Preconcentration (272)
Problem: Preconcentration needs rapid sorption, high binding affinity, good chemical selectivity, and good chemical stability
Project Activity Scope (from Technical Overview Chart): Mechanisms through Instruments
PNNL Solution:
- Install rigid, open pore, chemically specific sorbent layer on interface
- Novel morphologies tailored to multiple analytical methods (films, capillaries, etc.)
- Metal loading can be interrogated spectroscopically, electrochemically or by radiodecay counting.
- Sub-ppb detection demonstrated in the laboratory
Capabilities Employed to Meet Client Needs: Nano-technology, ceramic fabrication/processing, surface chemistry; ceramic chemistry; glass chemistry; separations chemistry and processes; material sciences; materials synthesis and performance evaluation.
