摘要：
We 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.
