Organophosphorus chemical agents have been analyzed by surface-enhanced Raman scattering (SERS) spectrometry. Significant spectral enhancement was achieved with special substrates that were prepared with silver-coated microspheres. Organophosphorus compounds were easily and rapidly measured at nanogram levels. The SERS spectra of eight of these organophosphorus chemical agents are presented. The sensitivity and spectral selectivity of this new spectrochemical technique for trace organic analysis of toxic chemical agents are discussed. Analyses of a two-component mixture and contaminated soil sample extract are illustrated.
