Stripping Voltammetry with Semi-Circular Potential Waves: Reversible Systems

Publication date: Available online 11 July 2019Source: Journal of Electroanalytical ChemistryAuthor(s): Yuki Uchida, Enno Kätelhön, Richard G. ComptonAbstractWe investigate stripping voltammetry using a semi-circular potential wave. Our results show that the herein introduced method greatly amplifies the current compared to the conventional linear-sweep method and can thus markedly increase the sensitivity of voltammetric stripping over linear-sweep methods. The shape of the obtained voltammograms features a characteristic dependency on the analyte formal potential which may be exploited to gain additional selectivity.
