The methods such as transmission electron microscope (TEM), scanning electron microscope (SEM), x-ray photoelectron spectroscopy (XPS), reflection-absorption infrared spectroscopy (RAIRS), electrochemical impedance spectroscopy (EIS) and the x-ray diffraction (XRD) method were used for the characterizations of nanocomposites. The linearity and the detection limit of quercetin (QR) were 1.0x10(-8) - 1.0x10(-7) M and 2.0x10(-9) M, respectively. The modified glassy carbon electrode (FeNPs/2-AETGO/GCE) was applied to the determination of QR in food sample such as apple juice.eninfo:eu-repo/semantics/closedAccessquercetingraphene oxideiron nanoparticlescharacterizationArticle109774377532-s2.0-84945936756Q3WOS:000365101700072Q4
