Abstract Cr⁶⁺ in K₂Cr₂O₇, (NH₄)₂Cr₂O₇, and K₂CrO₄ aqueous solution showed the same new strong band of 794cm^-1 in surface enhanced Raman scattering (SERS) by using SERS silver substrates. This new feature could be assigned to a surface complex of silver and Cr⁶⁺, for instance Ag₂CrO₄. The feature of 794cm^-1 could be a fingerprint band for detecting pollutant Cr⁶⁺ in water from SERS by using the SERS active substrate of silver.
