Using a copper microelectrode of Γ‡5-mm diameter, the concentration of Se(IV) was determined by cathodic stripping voltammetry either from HClO 4 (0.1 M) or from NaClO 4 (0.1 M) supporting electrolytes. The preconcentration time of 15 s was chosen as optimal, and calibration graphs were constructed f
