Abstract: In this paper, the procedure of preparation of graphite-Teflon composite electrode(GTE) by coating was investigated.The coating consisted of a solid mixture 2.5 g(graphite 45%, Teflon 45% and PVC 10%) mixed with a solvent (THF: DMF=1:4 in volume) 0.8mL.Copper wires(=0.7 mm) were coated by the coating and heated at 200℃ for 5 min,and the GTEs were finished.They could be modified and changed into other metallic Tefloncomposite electrode only by electroplating in correspondent plating bath, such as mercury-cobalt-or copper-Teflon composite electrode.They had been applled to flow injection analy-sis by techniques of electrochemitry successfully.

Key words: Graphite-Teflon composite electrode, Flow injection analysis, Voltammetry, Constant potential amperometry
