A theoretical and experimental study of the waveform in potentiometric stripping analysis with a rotating mercury-film electrode-the reversible case.
The potential-time transient in potentiometric stripping analysis with a rotating mercury-film electrode is simulated digitally by means of the finite-difference Cranck-Nicolson method. Good agreement with experimental results is obtained. The relations between peak shape and signal duration for reversible analyte systems are discussed, and it is shown that severe peak overlap gives rise to distortions of the composite signal.
