Determination of Selenium(IV) by Cathodic Stripping Voltammetry Using a Copper Microelectrode
Using a copper microelectrode of ∼5-μm diameter, the concentration of Se(IV) was determined by cathodic stripping voltammetry either from HClO4(0.1M) or from NaClO4(0.1M) supporting electrolytes. The preconcentration time of 15 s was chosen as optimal, and calibration graphs were constructed for the...

| description | Using a copper microelectrode of ∼5-μm diameter, the concentration of Se(IV) was determined by cathodic stripping voltammetry either from HClO4(0.1M) or from NaClO4(0.1M) supporting electrolytes. The preconcentration time of 15 s was chosen as optimal, and calibration graphs were constructed for the applied concentration interval 5 to 50 μM.Satisfactory reproducibility was obtained, with a standard deviation for 5 μMconcentration (n= 10) of about 4%. |
