摘要: The kinetics of the two-dimensional condensation 2-thiohydantoin deposited at interface mercury/non-aqueous acetonitrile/tetraethylammoniumperchlorate has been analysed for different electrode potentials by time dependent differential capacitance. various temperatures, concentrations and is explained a dynamic equilibrium adsorbate clusters. This involves compensation center growth periphery desorption condensed molecules lying inside center. islands have constant size which depend on potential electrode. A corresponding formula coverage-time dependence derived. The process during may be influence noncondensed come from bulk solution attack surface permanently. assumption proofed analytically. The water phase transition in acetonitrile some experiments. experimental results compared with those nonaqueous solution. The stabilised film investigated. adsorption holes. It found that existence holes single solution.
