Abstract

The possibility of using surface enhanced Raman scattering (SERS) detection method for bromate-anion determination and quantitative evaluation in water has been demonstrated for the first time. The decreasing of Rhodamine 6G (R6G) Raman peaks intensity has been used as the analytical signal corresponding to the catalytic oxidation by bromate. Electrostatically immobilized silver nanoparticles have been proven as efficient SERS-active substrate. A linear relationship between the Raman intensity of Rh6G as a function of BrO3 - was observed in the range of 0 - 10-7 M and the detect limit was as low as 10-10 M (nearly 0.01 μg/L). The results prove the potential of the proposed method for further application in the development of new portable SERS-based sensors for drinking water monitoring with high sensitivity, simplicity and the low cost.
