Description	Formation and properties of thiol (HS(CH2)10COOH or HS(CH2)10CH3) monolayers were investigated at stationary electrodes based on silver, copper, bismuth and cadmium solid amalgams covered by a mercury meniscus or by a mercury film (m-AgSAE, MF-AgSAE, m-CuSAE, m-BiAgSAE and m-CdSAE). For comparison, parallel experiments were performed at a classical hanging mercury drop electrode (HMDE). Thiol monolayers were prepared at an optimal deposition potential (e.g., for HS(CH2)10COOH Eac = 350 mV for HMDE and silver amalgam electrodes, Eac = 750 to 800 mV for m-CuSAE and m-BiAgSAE, and Eac = 1050 mV for m-CdSAE) at which the formed layers exhibit high density and stability. It was found that the potential of a reductive desorption peak of a thiol monolayer strongly depends on the metal which forms the amalgam (for HS(CH2)10COOH: Ep = 864 to 859 mV for HMDE and silver amalgam electrodes, Em-BiAgSAE = 1079 mV, Em-CuSAE = 1136 mV and Em-CdSAE = 1248 mV).
