Abstract

A relationship was derived for the resolution of differential pulse polarography as a function of the pulse amplitude and various parameters of the electrode reaction of the simultaneously present components(number of electrons exchanged in the electrode reaction, half-wave potentials). The resolution was found to be higher at small pulse amplitudes and large difference in the half-wave potentials. Resolution is higher when the number of electrons involved in the electrode reaction of both the measured and the interfering species are larger and it is mainly affected by the latter. The resolution of differential pulse polarography was found to be inferior to that of fundamental harmonic and second harmonic a.c. polarography. © 1986, The Japan Society for Analytical Chemistry.
