▎ 摘　　要

NOVELTY - The method involves utilizing an ITO conductive glass as working electrode. Potential electro-deposition reduction is performed on graphene oxide water dispersion constant. A graphene modified electrode is obtained. A copper sheet is laminated with same area as the graphene modified electrode. The graphene modified electrode is attached with a PTEB film after reaction is finished. A graphene/PETB photoelectrode is obtained. Neutral electrolyte solution is selected from phosphate buffer solution, tri-hydroxymethyl aminomethane-hydrochloric acid buffer solution and sodium solution. USE - Method for manufacturing graphene/PETB photo-electrode (claimed). ADVANTAGE - The method enables realizing the quick and direct detection of the penicillamine and othermercap to small molecule compound, ensuring better detection performance, and reducing shortage of the current analysis process. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a method for manufacturing graphene/PETB photo-electrode. (Drawing includes a non-English language text).
