NOVELTY - The utility model claims a detecting nitrogen-doped graphene preparing bisphenol A silk screen printing electrode sensor. Screen printing for the sensor is on the p-phthalic acid diethyl ester electrode substrate, doped with a conductive carbon ink working electrodes of conductive carbon printing ink printing ;Ag/AgCl ink printing auxiliary electrode reference electrode, a back electrode drying, checking to obtain the screen printing electrode electrochemical sensor is bisphenol A. As a screen printing electrode of sensor material is nitrogen-doped graphene which can increase the conductivity of the electrode, improves the detection sensitivity and stability of the sensor. This utility model claims a kind of low cost, simple and fast, electrochemical sensor for detecting bisphenol A of high sensitivity and in a very simple and easy, and it is easy to popularize and commercial 30 s, finishing detection.
