摘要: We reported a graphene-based electrochemical sensor for sensitively measuring carbendazim, which is one of the effective benzimidazole fungicides popularly used in agriculture. The β-cyclodextrin-functionalized reduced graphene oxide (β-CD–RGO) nanocomposites were synthesized using hydrazine as reducing agent at room temperature. as-synthesized characterized different analytical methods including UV–visible spectroscopy and Fourier transform infrared spectroscopy. with combination physicochemical properties RGO high molecular recognition capability β-CD to modify surface glassy carbon electrode determination drug carbendazim cyclic voltammetry differential pulse voltammetry. current responses on β-CD–RGO-modified greatly enhanced compared that bare due electrocatalytic effect β-CD–RGO. It was found peak currents increased linearly concentration range between 0.1 40 μM. obtained results suggest β-CD–RGO composite could be potential candidate preparation sensors or similar drugs future.
