| Abstract: | The electrode modified with ionic liquid and montmorillonite was prepared and characterized by electrochemical impedance spectroscopy.The content of carbendazim was determined by using differential pulse voltammetry.The modified electrode showed a good linear current response for carbendazim in the range of 5.0×10-7mol/L to 1.5×10-5mol/L by differential pulse voltammetry with a detection limit of 2×10-7 mol/L and a correlation coefficient of 0.9924.The electrochemical method can be used for the determination of carbendazim in solution. |
