Abstract
The adsorption of 2-thiouracil at the mercury-water interface exhibits several regions. In region I, the capacitance is consistently higher than that of the supporting electrolyte, as is usually observed for sulfur-containing compounds. At higher concentrations of 2-thiouracil, two additional adsorption regions appear. Region II corresponds to a condensed monolayer, formed by nucleation and two-dimensional growth, while region III exhibits behavior typical for polylayer formation.
