Adsorption of uranyl-hydroxo species has been studied using square-wave cathodic stripping voltammetry (SWCSV). The peak of the many1 ion between pH 5 and 8 has the characteristic features of a reduction complicated with reactant adsorption. The reduction process is totally irreversible, with an ave

Square-wave voltammetric measurements of the Eu(III)-salicylate (Eu-Sal) complex in 0.55 mol 1-l NaCl at pH 5.3 were made. At various europium concentration levels (from 10-s to 10e6 mol 1-r) the redox process of the Eu-Sal complex is reversible, with adsorption of the reactant of the redox reaction
The effects of changing certain parameters of the applied potential waveform at a dropping mercury electrode (DME) in square-wave voltammetry (s.w.v.) were investigated and compared with theory. Optimum parameters of the waveform are determined for a reversible system, lead(I1) in 0.10 M perchloric
