This paper presents the study of the adsorption capacity of some anions on RuO_2·TiO_2 by surface enhanced Raman scattering (SERS). We deposit silver on the surface of RuO_2·TiO_2 to obtain a SERS-active surface. Experimnent indicates that the adsorption capacity is in the following sequence: Cl~->OH~->PO~(3-)_4>SO~(2-)_4>NO~-_3. This paper also gives a discussion of the adsorption pattern of probe molecule on RuO_2·TiO_2/Ag.

Key words: Surface enhanced Raman scattering, Adsorption, RuO2?TiO2, Anions
