AB  - In the present study, a novel triple-wavelength overlapping resonance Rayleigh 
      scattering (TWO-RRS) method had been well established to detect perfluorooctane 
      sulfonate (PFOS). We found that crystal violet (CV) could react with PFOS to form 
      1:1 ion-association complex by electrostatic attraction and hydrophobic effect 
      over a wide pH range (5.0 approximately 11.0) in less than 60 s. The complexes would further 
      self-aggregated into nanoparticles [CV-PFOS]n. Based on this phenomenon, not only 
      the absorption and Raman spectra were changed but also the resonance Rayleigh 
      scattering (RRS) intensities were significantly enhanced. And three new RRS peaks 
      located at 327, 492, and 654 nm were clearly observed, respectively. At the same 
      time, it was found that both the enhanced single-wavelength resonance Rayleigh 
      scattering (SW-RRS) and TWO-RRS intensities against the concentration of PFOS 
      showed an excellent correlation. The detection limits for the three single peaks 
      were 27.4 nmol L(-1) (13.7 mug L(-1), 327 nm), 27.5 nmol L(-1) (13.8 mug L(-1), 492 
      nm), and 31.4 nmol L(-1) (15.7 mug L(-1), 654 nm), and for TWO-RRS method was 5.9 
      nmol L(-1) (3.0 mug L(-1)). Moreover, it could be applied to determine PFOS water 
      samples successfully.
