Very low frequency (down to 3 × 10−3 Hz) impedance measurements on a hanging mercury drop electrode

Résumé

The authors describe an experimental set-up, using transfer function analysers, which allows for the impedance of a hanging mercury drop electrode to be measured at frequencies as low as 3 × 10−3 Hz, and for the low frequency limit of that impedance to be compared with the slope of the current-voltage curve. The device is applied to the reduction of the persulfate anion in a 1 M LiCl solution, in a region of potential where the current-voltage curve has a negative slope.
