Abstract
In this study, we propose a simple and low-cost procedure by using boron-doped diamond (BDD) as a working electrode to detect amodiaquine (AQ) in phosphate buffer solution (PBS) and potassium perchlorate (KClO4) electrolytes. We used cyclic voltammetry (CV) and different pulse voltammetry (DPV) techniques. By using DPV, oxidation of AQ in PBS and KClO4 was observed at + 0.28 V and + 0.4 V (vs. Ag/AgCl), respectively. To investigate the redox reaction mechanism, the pH and scan rate were varied. A linear calibration curve was observed in the concentration range of 0.0645 – 0.3 µM with a detection limit of 1.47 × 10−3 µM (S/N = 3) for PBS and 4.81 × 10−3 µM (S/N = 3) for KClO4. This result confirms that BDD electrodes could potentially be used to detect AQ.
