AB  - A triple-wavelength overlapping resonance Rayleigh scattering (TWO-RRS) method 
      was developed to detect dextran sulfate sodium (DSS) with crystal violet (CV). At 
      pH 10.0 Britton Robinson buffer solution medium, the interaction of CV with DSS 
      occurred which greatly enhanced the RRS intensity with the new RRS peaks 
      appearing at 340, 501 and 671 nm and all these three peaks enhanced with the 
      increase of DSS concentration in the range of 0.04-2.5 microg ml(-1) and the 
      detection limit for the three single peaks was 0.024, 0.027, and 0.027 microg 
      ml(-1), respectively, whereas that of the TWO-RRS method was 0.013 microg ml(-1). 
      The TWO-RRS method was found to have much better flexibility and high sensitivity 
      than the single-wavelength method. In this paper, the interaction conditions were 
      optimized. The affecting factors and characteristics of RRS for the interaction 
      of DSS with CV were investigated and a sensitive method for the determination of 
      trace amounts of DSS using the TWO-RRS method was developed.
