Theory of potentiometric stripping analysis in the case of reversible and quasi‐reversible electrode reactions

Abstract

The theoretical treatment of potentiometric stripping analysis is presented for the cases of reversible and quasi-reversible electrode reactions. The experimental results were found to be in good agreement with calculated data. Derivations based on different assumptions (e.g., stripping in stirred solutions, diffusion layer of constant thickness) are compared.

“…So the maximum sample time was only limited by free disk space. After the measurement the transition time T as the quantitative analytical signal [6,7] was determined by a tangent [8] (Fig. 2) or histogram [9] method.…”
