| Abstract: | The dependence of SERS intensity ISERS on the concentration c is studied experimentally for salicylic acid (SA) aqueous solution-Ag mirror system by measuring ISERS And the relation between ISERS and quantity of adsorbed molecules is also discussed. All the results suggest that the SERS technique indeed provides a efficient and high sensitive new method for studying adsorption isotherm property in solid-liquid system. |
