OPTIMIZING CONCENTRATION DETERMINATIONS IN PRESENCE OF MAXIMA AND CATALYTIC AND KINETIC WAVES USING VIBRATING DROPPING MERCURY ELECTRODE

Studies with the vibrating dropping mercury electrode (VDME) at different vibrational frequencies demonstrate that the VDME is significantly superior to the DME for most analytical purposes. At a frequency of 210 Hz (drop times about 5 msec), maxima of the first and second kinds are suppressed at the VDME without the addition of surfactants. Catalytic and kinetic currents can also be minimized or eliminated at the VDME at this frequency. In addition, the VDME permits the analysis of agitated solutions. © 1969, American Chemical Society.
