Experimental verification of theory and implications for sonovoltammetry

Article Abstract:

Anodic stripping voltammetry experiments were performed to investigate the potential application of square wave voltammetry (SWV) together with ultrasound. An aqueous lead solution with mercury thin film electrodes was examined. The findings support the theoretical basis of SWV application to electrochemical reversible systems undergoing anodic stripping voltammetry. The application of power ultrasound correlated well with the high mass transport. Moreover, the mass transport at the electrode surface was identified as the dominant effect of acoustic streaming.

Simulation of square wave voltammetry: quasi-reversible electrode processes

Article Abstract:

It has been possible to develop simulations for the square wave voltammetry experiment for the general case of quasi-reversible Butler-Volmer kinetics and a finite diffusion layer thickness. This work is to be extended to coupled homogenous kinetics and microelectrode geometries.

Heterogeneous and homogeneous EC and ECE processes at channel electrodes: analytical wave shape theory

Article Abstract:

The analytical theory of EC and ECE processes at channel electrodes has been developed for both heterogeneous and homogeneous chemical reactions with regard to the voltammetric wave shape and the impact of the cell geometry and the coupled chemistry on the half-wave potential.
