چکیده
|
In this work, a sensitive sudan i electrochemical sensor was assembled using nife_2o_4 nanoparticles modified screen printed electrode. due to the synergetic effect of nife_2o_4 nanoparticles displayed high electrochemical activity with well-defined voltammetric peaks of sudan i oxidation and lower overpotential compared with unmodified electrode. according to the results of differential pulse voltammetry (dpv), under optimized conditions, a good linear response was observed for the concentration of sudan i in the range of 0.1–100.0 μm with a detection limit of 0.05 μm. the developed electrochemical sensor was successfully applied to determine sudan i in water samples. this study indicated that nife_2o_4 nanoparticles based electrochemical sensor can be a promising and reliable tool for rapid analysis of sudan i.
