In this paper, the SERRS of BATD has been investigated, the effect of pH, concentration and electrolyte on SERRS was discussed and the adsorbed state of BTAD was figured. We suggest that the adsorbed state of BTAD is the bonding of benzotriazol to Ag surface via lone pair electron on the nitrogen. With HCl and ascorbic acid aggregate Ag sol, the dependence of SERRS on BTAD concentration behaves differently. In the former case, the adsorbed state changes, but in the latter it remains the same. Small amount of electrolyte will induce the active sites on the surface, but when it is more than 1×10-2mol﹒L-1, the competent adsorbtion reduces the Raman scattering intensity. Hydrogen ions protonize BTAD to BTAHD and reduce the contribution of lone pair electron on N atom of the conjugated system.
