Abstract

The experimental verification of a new multi-impulse electroanalytical method, multiple square wave voltammetry (MSWV), in which several impulses of constant amplitude are superimposed on each step of a staircase waveform is presented. In particular, it has been confirmed that the voltammograms, obtained from current or charge measurements at a SMDE using the reversible couple Fe(II)/Fe(III) in oxalate medium, can be adequately interpreted in a very simple way. The analysis of experimental data still remains valid when a large number of impulses are applied to each step of the potential staircase. This yields a considerable improvement in real sensitivity at low concentrations.
