摘要：
A simple method for direct and quantitative determination of carbendazim using electrochemically reduced graphene oxide modified glassy carbon electrode (ERGO/GCE) has been developed. The obtained electrode was characterized using scanning electron microscopy, Raman spectroscopy, cyclic voltammetry and differential pulse voltammetry. Compared to bare and graphene oxide modified electrodes (GO/GCE), the ERGO/GCE not only significantly shifted to a lower positive potential, but also noticeably enhanced the current response. The resulting carbendazim sensor showed a wide linear range (2.0 nM to 400 nM) and a low detection limit (1.0 nM). In addition, the proposed sensor has excellent selectivity, good stability and can be successfully applied in soil sample. The ERGO, which was obtained by facile, cost-effective method, could provide a promising platform to develop excellent electrochemical sensors for detecting carbendazim.
