摘要：

A surface enhanced resonance Raman scattering (SERRS) procedure is described for the analysis of acidic monoazo dyes. The SERRS spectra of these compounds can be obtained if a 0.01 % solution of poly(L-lysine) is added to a citrate-reduced silver sol. Further enhancement of the SERRS intensities can be obtained by the addition of ascorbic acid. The discrimination between dyes offered by this procedure is demonstrated and a mechanism is proposed for the interaction between the poly(L-lysine), ascorbic acid and a dye.
