다국어 초록 (Multilingual Abstract)

A facile synthesis strategy of reduced graphene oxide (RGO)‐octahedral Mn3O4 (oct‐Mn3O4) nanocomposites using in situ one‐pot hydrothermal reaction was reported. The RGO‐oct‐Mn3O4 nanocomposites were drop‐casted onto the surface of glassy carbon electrode (GCE) to obtain RGO‐oct‐Mn3O4/GCE. DPV results revealed that the performance of RGO‐oct‐Mn3O4/GCE towards metronidazole displayed a linear ranging from 0.1 to 9.5 μM with a detection limit of 0.037 μM. For sulfamonomethoxine, it exhibited a linear ranging from 1 to 95 μM with a detection limit of 0.27 μM. Moreover, the proposed sensor had good anti‐interference capability, high stability, satisfactory reproducibility, and was successfully applied in real samples.
