Electrosorption of Organic Molecules

摘要

The maximum bubble pressure method was used to measure the interfacial tension of the mercury-solution interface in the presence of thymine. This particular adsorbate was selected because it can form, over a range of concentrations and potentials, a condensed film at the mercury-water interface. A simple method was developed to determine, separately, the faradaic and charging components of the polarographic current, based on the different time-dependencies of these two components. Condensed thymine monolayers inhibit many electrode reactions. With these monolayers the surface pressure can be varied (by varying the bulk thymine concentration) without changing the composition of the film or its charge density. Research completed on thymine provides a uniquely thorough and comprehensive account of the thermodynamics and kinetics of film formation, a subject of considerable practical importance in corrosion protection, a subject of considerable practical importance in corrosion protection. Developed were a number of novel ideas and new experimental approaches.
