Abstract:

Surface Enhanced Raman Scattering (SERS) of tetrasodium meso-tetrakis (4-sulfonatophenyl) porphine (H2TSPP) and silver tetraphenylporphyrin (Ag(Ⅱ)TSPP) adsorbed spontaneously on uniform Fe3O4 colloids are recorded. The enhancement of Raman bands is approximately 30. An analysis of the SERS spectrum shows that on the Fe3O4 surface H2TSPP takes its diacid form H42+TSPP.

Key words: Meso-tetrakis(4-sulfonatophenyl) porphine(H2TSPP), Uniform Fe3O4 colloids, Surface Enhanced Raman Scattering(SERS), Protonation
