Abstract:
A new method to study chemical adsorption kinetics by means of surface enhanced raman scattering is proposed. The theoretical model is proposed and experimental results given out. The adsorption of CV and PABA molecules on the surfaces of silver mirrors and silver colloids is studied. It is found that the adsorption of CV on silver surfaces is homogeneous, and the adsorption of PABA is heterogeneous. The differences of silver surfaces only influence the adsorption rate constant Ka, not changing the heterogeneity character of adsorption and desorp-tion rate constant (Kd=0). Finally, the significance of heterogeneity paramter is discussed.
