High performance of screen-printed graphite electrode modified with Ni-Mo-MOF for voltammetric determination of amaranth
Original language description
The present study introduces a novel Ni-Mo-MOF-modified screen printed electrode (Ni-Mo-MOF/SPE) to sensitively and rapidly detect amaranth. Cyclic voltammetry (CV) was also applied to evaluate the electrochemical behavior of amaranth on the surfaces of bare SPE and Ni-Mo-MOF/SPE, and differential pulse voltammetry (DPV) to calculate linearly detection range of amaranth. According to the results, various linear oxidation peak currents were obtained at different concentrations (between 0.15 +/- 0.001 and 500.0 +/- 0.001 mu M) and the limit of detection (LOD) was estimated to be 0.05 +/- 0.001 mu M in the optimal conditions. Additionally, the efficacy of developed electrode was tested by real samples, the results of which were satisfactory. The proposed Ni-Mo-MOF/SPE not only had special properties such as high selectivity, high sensitivity, cost-effectiveness and rapid response, but also was shown to possess wide applications for sensitively amaranth detection in real samples.
