Rutin is a class of flavonoids. Flavonoids have crucial antioxidant and chelating properties and are present in fruits and vegetables. Despite of their elusive metabolism, the enteric absorption reduces plasma oxidant status. Due to these reasons, rutin detection is important based on sensitive method. In the present report, a new electrochemical sensor based on CoFe2O4 nanoparticles ionic liquid nanocomposite was developed for rutin analysis in orange juice samples. Firstly, the structure analysis of prepared nanocomposites was characterized by transmission electron microscopy, cyclic voltammetry, X-ray photoelectron spectroscopy, electrochemical impedance spectroscopy and energy dispersive X-ray analysis. The linearity range and detection limit of the prepared sensor were obtained as 1.0 x 10(-10)-1.0 x 10(-8) and 3.0 x 10(-11) M, respectively. In addition, the voltammetric sensor was applied to orange juice samples with high recovery. (C) 2017 Elsevier B.V. All rights reserved.
