In-situ modified antimony-film glassy carbon electrode for metal trace analysis
Journal Title: Proceedings of the International Conference on Advanced Materials and Systems (ICAMS) - Year 2018, Vol 1, Issue
Abstract
Glassy carbon electrodes (GCE) have been extensively employed for the determination of trace amounts of heavy metals. Lately, modifications of GCE are currently being sought. One way of obtaining better analytical performance compared to GCE is the employment of an in situ prepared antimony-film glassy carbon electrode (SbFE). This combination is especially attractive in anodic stripping voltammetry technique which uses square wave excitation signal. This work will report on the optimization of the in situ prepared SbFE by employing different deposition potentials. Furthermore, a preliminary study using electrochemical impedance spectroscopy (EIS) was performed at different deposition and measured potentials in order to understand the mechanism of SbFE sensor performance.
