Abstract
The direct chemical deposition of silver on HCl-etched iron surface was first found to be able to present a SERS-active iron substrate. This method was used to study the adsorption of 2-mercaptoethanol on iron surface. For the propose of comparison, the adsorption of this substance on silver mirror was investigated. The results compounds could be chemisorbed HCl-etched iron plate and silver mirror surface in similar state and form a self-assembled monolayer of their thiolates.
