▎ 摘　　要

NOVELTY - The electrode has a polyfluortetraethylene tube or quartz glass tube whose inner side is filled with carbon paste, where inner diameter of the polyfluortetraethylene tube or glass tube is 3 mm. A terminal of an electrode lead is directly coated with the carbon paste and another terminal of the electrode lead is fixed out to the polyfluortetraethylene tube or glass tube. The graphite powder, solid paraffin oil and graphite /SDS composite material are uniformly mixed in a ratio of 3-5: 1.07-1.6: 1. Press quality of the graphite /SDS composite material is 1: 0.3-0.4. USE - Graphene/SDS modification modified carbon paste electrode. ADVANTAGE - The electrode has good electrochemical activity, good repeatability and stability and dopamine check, and is easy to activate and regenerate. DETAILED DESCRIPTION - The electrode lead is copper rod, silver rod or stainless steel bar. An INDEPENDENT CLAIM is also included for a graphene/SDS modification modified carbon paste electrode preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene/SDS modification modified carbon paste electrode.
