## Abstract Underpotential deposition (UPD) and stripping of Pb^2+^ at thiolβbased disorganized monolayerβmodified gold electrodes was studied by cyclic voltammetry (CV) and electrochemical quartz crystal microgravimetry (EQCM). Electrodes modified with mercaptoacetic acid or mercaptoethane sulfoni
This work describes the study of underpotential deposition (upd) of Pb on polycrystalline platinum in 0.2 M HCIO, solutions using cyclic voltammetry and rotating ring-disk electrode techniques. In such conditions, a full monolayer of upd Pb corresponds to a coverage of 0.41. The adsorption of lead i
