▎ 摘　　要

NOVELTY - The sensor has a graphene-Nafion (RTM: sulfonated tetrafluororthylene) glassy carbon electrode connected with a silver/silver chloride reference electrode. An auxiliary electrode is made of molybdenum. The graphene-Nafion (RTM: sulfonated tetrafluororthylene) glassy carbon electrode is made by a surface modified material and a dispersing agent using an ultrasonic wave vibration process. USE - Sulfonamide pyridine electrochemical sensor. ADVANTAGE - The sensor has fast response, better stability, high sensitivity and linear range. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating characteristics of a sulfonamide pyridine electrochemical sensor. '(Drawing includes non-English language text)'
