The method can also be used for the detection of trace quantities of metal impurities in solids or solutions. Collaborative analytical projects with outside users are currently underway. The research program that is underway at the Center involves synthesizing new complexants that are selective for extracting metals from both soils and waters, and determining the optimal molecular geometries and stereochemistries that allow for extraction into selected fluids. Computational facilities are available for carrying out molecular mechanics calculations on different molecular structures. These computational faciltities include a DEC alpha 433 workstation server interfaced with a Silicon Graphics Octane computer.
Software is available to study both organic molecules and metal complexes by computational methods.
