Abstract: Molecularly imprinted polymers (MIPs) that can selectively extract and concentrate aqueous contaminants are being developed for quantifying trace levels of microcystins, pesticides, odorous compounds, pharmaceuticals, and mycotoxins. MIP technology is particularly powerful because even nanogram or picogram amounts of an analyte can be extracted from structurally similar compounds and subsequently desorbed for quantitation by other methods. We have explored coupling MIPs with Raman spectroscopy and surface enhanced Raman spectroscopy (SERS) for detection of atrazine, microcystin-LR, and 2-methylisoborneol. SERS has been employed infrequently in the drinking water field, but recently asserted itself as a viable method for chemical quantification in biological cells, blood plasma, or groundwater at levels as low as femtomolar. Results of our work demonstrate that MIPs can be transformed into self-supported filters to facilitate contaminant concentration, and Raman spectroscopy can confirm the presence of targeted analytes within a MIP. Insight into the current progress, possible impact, and potential use of MIPs and SERS by the water industry for contaminant monitoring is provided. Successful coupling of MIPs for drinking water contaminants and SERS analyses would be a practical and significant achievement in regards to water quality monitoring of trace contaminants. 2010 -® American Water Works Association WQTC Conference Proceedings All Rights Reserved
