Electrochemical detection of aspartame on glassy carbon electrode

Aspartame is one of the artificial sweeteners, which if it consumed in excess of the prescribed limits will promote negative effects such as headaches, dry mouth, and seizures. In this report, an electrochemical sensor for detecting aspartame is investigated by using square wave voltammetry (SWV) technique in phosphate buffer solution (PBS). In this study, aspartame analysis utilized glassy carbon electrodes (GCE) as working electrodes, platinum as counter electrodes, and Ag/AgCl as reference electrodes. The linear range was in the concentration range of 30 - 100 µM with limit of detection of 3.66 µM. The results also show the satisfactory of reproducibility with RSD of 2.20 %.
