We suggest that the adsorbed state of BTAD is the bonding of benzotriazolto Ag surface via lone palr electron on the nitrogen. With HCl and ascorbic acid aggre-gate Ag sol, the dependence of SERRS on BTAD concentration behaves differently. Inthe former case, the adsorbed state changes, but in the latter it remains the same. Smallamount of electrolyte will induce the active sites on the surface, but when it is more than1×102zmol L-1, the competent adsorbtion reduces the Ratnan scattering intensity.
