【 摘 要 】

The objective of the Empore membrane technology is to allow rapid and economical field sampling of surface and subsurface waters for heavy metal and radionuclide contaminants. At this time, membranes for the following elements have been tested: strontium (Sr), technetium (Tc), cesium (Cs) and lead (Pb). Analysis of the sampled contaminants is subsequently performed either in the field or at a remote analytical laboratory. Applications of this technology include routine monitoring of sites having known contamination and the characterization of sites where the extent of contamination has not yet been determined. Samples for assay may originate from surface waters or from the subsurface via monitoring wells. DOE sites with significant surface or groundwater monitoring programs include Savannah River, Fernald, Oak Ridge, Rocky Flats and Idaho. The baseline method for assay of site water for heavy metal and radionuclide contamination is to obtain samples and then to transport the samples to chemical laboratories for time-consuming chemical separation and analysis.
