Alternating Current Polarography: Evaluation of the Accuracy of the Data and Calculation Procedures

Abstract

The accuracy of the data obtained by A.C. polarography when measuring electrode parameters and in analytical work is discussed in a critical review of the actual measurements and calculations involved. The importance of correcting for the series resistances and of using equations which take into account the phase differences between the faradaic and capacitative currents is demonstrated. Other subjects discussed include the nature of the dependence of the peak alternating current on depolarizer concentration, effect of adsorption of depolarizer on the electrode, and simplified procedure for quantitative analysis.
