الوصف: | Ag-doped Fe3O4 nanoparticles (Ag-Fe3O4) was successfully synthesized by the hydrothermal method and performed a simple chemical reaction process in a significantly shorter time than traditional solvothermal method. Furthermore, Ag-Fe3O4 electrochemical sensor was prepared using chitosan and acetic acid as crosslinkers, and the electrochemical behavior of methomyl on the electrode was studied by cyclic voltammetry. Experimental results showed that the electrode had faster response, higher detection sensitivity and better stability for methomyl. Under optimal conditions, the linear current response was achieved in the concentration range of 2.97×10-5 mol·L-1~3.47×10-4 mol·L-1, with the detection limit of 2.08×10-5 mol·L-1. The methomyl in different vegetable samples was detected, and its recovery rate was between 90%~98%. |
