In pH 2.00～3.42 Britton-Robinson(B-R) buffer medium, Rhodamine 6G can react with sodium dodecylbenzene(SDBS) and sodium dodecyl sulfate(SDS) to form ion-association complexes. As a result, an enhanced resonance rayleigh scattering(RRS) spectra was observed, and the maximum RRS wavelengths of ion-association complexes were located at 375 nm.The detection limits of SDBS and SDS were 6 ng/mL and 5 ng/mL, and the linear ranges were 0.02～5.6 and 0.02～14.0 μg/mL, respectively. The method has been applied to the determination of SDBS and SDS in simulated and environmental samples with satisfactory results.
