title: Surface layers of 6-thioguanine on the mercury electrode.
abstract: The adsorption behavior of 6-thioguanine (6TG) on a hanging mercury drop electrode has been studied with ac and cyclic voltammetry in 0.1 M Na2SO4 and 0.01 M sodium acetate solutions at pH 4.3. Several condensed phases of chemically adsorbed 6TG as well as one phase of physically adsorbed 6TG have been characterized. Under total coverage conditions, the films of chemiadsorbed molecules inhibit rather efficiently the electrode reaction of mercury oxide formation.
