Abstract

Nitrogendoped graphene oxide NGO was synthesized via pyrolysis of graphene oxide and urea and was characterized by transmission electron microscopy TEM and Xray photoelectron spectroscopy XPS An electrochemically reduced nitrogendoped graphene oxidemodified glassy carbon electrode ERNGO/GCE was developed for the determination of carbendazim CBZ in food samples The surface morphology of the modified electrode was characterized by scanning electron microscopy SEM Cyclic voltammetry and electrochemical impedance spectroscopy were employed to demonstrate the large electrode surface and fast electron transfer of the ERNGO/GCE Electrochemical behaviors of CBZ at different electrodes were studied by voltammetry Experimental results showed that the ERNGO/GCE achieved better performance for the electrochemical oxidation of CBZ than either the bare glassy carbon electrode GCE or the nitrogendoped graphene oxidemodified GCE NGO/GCE Under optimized conditions the ERNGO/GCE exhibited a wide linearity of 50~850 μg/L with a detection limit of 10 μg/L signaltonoise ratio = 3 Application of our proposed method in food products was shown to be practical and reliableThis work was financially supported by the Natural Science Foundation of Guangxi for Youth No 2015GXNSFBA139037 the Fundamental Research Funds for the Guangxi Academy of Agricultural Sciences 2015YT94 and the Achievement Transformation Project of Guangxi Academy of Agricultural Sciences 2016020This study was funded by the Natural Science Foundation of Guangxi for Youth No 2015GXNSFBA139037 the Fundamental Research Funds for the Guangxi Academy of Agricultural Sciences No 2015YT94 and the Achievement Transformation Project of Guangxi Academy of Agricultural Sciences No 2016020Yu Ya declares that he has no conflict of interest Cuiwen Jiang declares that he has no conflict of interest Leixing Mo declares that he has no conflict of interest Tao Li declares that he has no conflict of interest Liping Xie declares that he has no conflict of interest Jie He declares that he has no conflict of interest Li Tang declares that he has no conflict of interest Dejiao Ning declares that he has no conflict of interest Feiyan Yan declares that he has no conflict of interest
