Thiolate monolayers formed on different amalgam electrodes. Part II: Properties and application

Popis výsledku v původním jazyce

Properties of thiol monolayers were investigated at electrodes of solid amalgams of silver, copper, bismuth, cadmium (MeSAE) and at hanging mercury drop electrode (HMDE). The concentration dependences of studied thiol (HS(CH2)10COOH; MUA) at HMDE, m-AgASE, MF-AgSAE and m-CuSAE were similar for all electrodes and the Langmuir equation was used for evaluation of obtained results. Calculated values of DGads were very close for all electrodes. The lowest saturated surface coverage was observed for HMDE (8.51010 mol cm2) and the highest one for MF-AgSAE (9.8 1010 mol cm2). Nonlinear dependences of the peak currents on the scan rate show that lateral interactions exist among adsorbed molecules. When the scan rate is increased, the negative value of the peakpotential increases proportionally with the natural logarithm of the scan rate. The potential of the desorption peak is almost unchanged if the thiol surface coverage (H) is 50% or lower. At higher values of H the adsorbate molecules att
