Embodiment 1
[0014] 1. Treatment of glassy carbon electrodes
[0015] The glassy carbon electrode was polished with 1.0 μm, 0.3 μm and 0.05 μm alumina powder on a polishing cloth in turn, then placed in nitric acid with a volume ratio of 1:1 for 8 minutes, and then placed in absolute ethanol for 8 minutes , and finally ultrasonically cleaned with pure water.
[0016] 2. Preparation of molecularly imprinted electrochemical sensor for valerenamide
[0017] To 10.0 mL of solvent ethanol, add 1.0 mmol of template molecule provalerianamide, 4.0 mmol of functional monomer young branch containing broken oxyloganin, 4.0 mmol of cross-linking agent N-trans-feruloyl tyramide, 0.11 The nano-clay of mmol initiator azobisisobutyronitrile and 0.0500 g, each adding a kind of chemical reagent ultrasonic dissolving for 8 minutes;
[0018] Take 8 μL of the mixture in step and apply it on the surface of a clean and smooth glassy carbon electrode with a diameter of 2 mm. After standing for 6 hours, place...
