Abstrakt:
Electrochemical oxidation of a mephenoxalone (MNL) was firstly studied using boron doped diamond electrode (BDDE). At different pH, an irreversible anodic peak was observed at potential of +1.375 V (vs. Ag/AgCl). The voltammetric method for MNL determination was developed using square wave voltammetry. This method provides low limit of detection (5.5×10–8 mol L–1), wide linear dynamic range (1.0×10–7-3.0×10–5 mol L–1), and good recovery in the analysis of model samples as well as pharmaceutical preparation Dimexol 200 mg. The developed method was successfully transferred to the commercially available and lab-made screen-printed sensors with chemically deposited BDDE.
