Linear-Scan Anodic Stripping Voltammetry with Thin-Film Electrodes: Theory of the Stripping Stage and Experimental Tests

摘要

The principles of thin-layer anodic stripping voltammetry, are discussed and a model for the stripping stage is developed for anodization by a linear potential ramp. The model assumes uniformity of the amalgam concentration, reversible electrode behavior, and planar diffusion of the stripped ions away from the anode. The entire shape of the stripping peak is then predicted from the model. Several stringent tests are developed to assess how well the model accords with experimental reality.
