Some Factors Affecting the Precision in Polarographic Analysis

Abstract

The factors influencing the variables of the Ilkovic equation are analyzed. Tolerances in the control of the experimental conditions are estimated which permit chemical analyses or determinations of diffusioncurrent constants with a precision of ±2%. The presence of maxima in polarographic waves and the effect of their suppression on the diffusion current are discussed. Criteria are given for determining when the current is represented by the Ilkovic equation.
