| An array of environmental problems necessitates the development of rapid, portable, cost effective measurement systems of determining trace levels of contaminates. Nanostructured sorbents offer fast uptake kinetics, high material loading, and excellent selectivity. We have explored a number of methods for using these new materials synergistically with analytical instrumentation. We have found X-ray fluorescence coupled with nanostructured sorbents for solid phase microextraction to be capable of quickly determining the concentration of a number of toxic heavy metals at the EPA drinking water limits. Similarly, we have found that simple field portable nuclear counters are capable of selective sensitive radionuclide detection when appropriately coupled with nanostructured sorbents. We will discuss the advantages, challenges and limitations involved in using selected nanomaterials for improved methods of environmental characterization. |
