Abstracts
Methidathion, a non-systemic organophosphorous insecticide and acaricide is studied at
the hanging mercury drop electrode under cathodic stripping mode by means of cyclic and square-wave
voltammetry (SWV). Its electrode reaction is analyzed in the light of recent theory of cathodic stripping
processes of insoluble salts of SWV. Its complex electrode mechanism is described by an electrode
reaction of a second order, complicated by adsorption of methidathion molecules on the electrode surface
involving lateral interactions between each other. Moreover, under specific experimental conditions
the electrode mechanism can be additionally complicated by multilayer formation on the electrode
surface, as well as by a chemical transformation following the cathodic stripping process of the methidathion-
mercury salt. Following the mechanistic study of the electrode reaction, a method for quantitative
determination of methidathion is proposed applying SWV.
