▎ 摘　　要

NOVELTY - A screen printing electrochemical sensor has screen printed electrodes, a graphene oxide dispersion liquid layer coated on screen printing electrodes and an imidazole ionic liquid dispersion layer coated on graphene oxide dispersion liquid layer. The concentration of graphene oxide dispersion is 2-10 mg/ml. The amount of graphene oxide dispersion is 2-5 mu L. USE - Screen printing electrochemical sensor is used for detecting disposable trace amounts of carbendazim (claimed). ADVANTAGE - The screen printing electrochemical sensor efficiently detects disposable trace amounts of carbendazim with high accuracy and sensitivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of screen printing electrochemical sensor; and (2) application of screen printing electrochemical sensor for measuring concentration of carbendazim.
