	abstract = {The application of 1,9-nonanedithiol (NDT) self-assembled monolayer (SAM) on gold for the electrochem. detn. of Cd2+ was studied. A NDT SAM strongly affects the stripping wave of Cd, resulting in a sharp peak that was used for electroanal. detn. of Cd2+ in aq. solns. The different parameters, such as potential and time of deposition of Cd, were examd. Also, polarization-modulated IR reflection absorption spectroscopy (PM IRRAS) and XPS were used for exploring the interaction between the deposited Cd and the thiol groups on Au. FTIR measurements clearly indicate that NDT is assembled in a disordered liq. type monolayer interacting with the Au electrode via both thiol moieties. XPS reveals that Cd is stripped at two different potentials and that the signal of sulfur is almost unchanged by deposition and desorption of Cd. All these finding allude to the interesting conclusion that Cd is deposited on Au lifting to some extent the thiol groups. [on SciFinder(R)]},
