Description
Summary:In this work, a carbon paste electrode was modified with ionic liquids and NiMoO4 nanosheets (NMs/IL/CPE) for voltammetric epinine detection. The NMs/IL/CPE showed good electro­catalytic activity for epinine oxidation compared to unmodified CPE. The limit of detection is 0.05 μM, and under ideal circumstances, the oxidation peak currents of epinine show a linear relationship with epinine concentration from 0.1 to 300.0 μM. Additionally, when dobutamine was present, the NMs/IL/CPE showed good activity toward epinine determi­na­tion. Its appropriateness for the simultaneous detection of these two medicines using dif­ferential pulse voltammetry is shown by the separation of the oxidation peak potentials of 200 mV. Lastly, epinine and dobutamine analysis in real specimens confirmed the proposed sensor's applicability with outstanding findings (recovery 96.0 to 103.5 %, and relative standard deviation <3.6 %).
