Electrochemical determination of rutin by using NiFe2O4 nanoparticles-loaded reduced graphene oxide

A binary transition metal oxide containing nickel and iron (NiFe2O4) hybridization of this nanomaterial with reduced graphene (rGO) are synthesized by the hydrothermal method. X-ray diffraction (XRD) Raman spectroscopy confirm successful synthesis these materials. Also, scanning electron microscope (SEM) transmission (TEM) images illustrated particle morphology size 20 nm. The material is then examined as a sensor on surface glassy carbon electrode to detect very small amount rutin. Some electrochemical tests such cyclic voltammetry, differential pulse voltammetry (DPV), impedance indicate remarkable accuracy its operation in relatively wide range concentrations rutin (100 nM-100 µM). proposed sensors approximately 100 nM 0.1 M PBS, (pH = 3) which impressive can be reported. stability rate after DPV was about 95 %, considerable excellent value. Considering good results, it seems that NiFe2O4-rGO considered new proposal development accurate inexpensive sensors.
