Differential pulse anodic stripping voltammetry at the wall-jet electrode

Abstract

Differential pulse anodic stripping voltammetry at the wall-jet electrode requires careful consideration of flow conditions in the plating and stripping steps as well as the electrochemical parameters such as modulation amplitude and clock period. A systematic appraisal of the various factors affecting the differential pulse stripping current is described. Although the stripping current depends on the stripping solution flow rate, the differential pulse mode is preferred to dc stripping because of its greater sensitivity and the abililty to obviate oxygen interference. © 1986.
