▎ 摘　　要

NOVELTY - A graphene-modified electrode manufacturing method involves dissolving sample preparation-containing resveratrol in an acidic or neutral buffer solution to obtain a sample solution, using square wave voltammetry, and graphene-modified working electrode to measure resveratrol content in sample solution, where the graphene-modified electrode is produced by mixing peeling aids and graphite powder by adding stripping solvent hours to obtain graphene dispersion, followed by polishing glassy carbon electrode to mirror surface, coating the graphene dispersion liquid on the dried electrode surface. USE - Method for manufacturing a graphene-modified electrode. ADVANTAGE - The method enables manufacturing the graphene-modified electrode with high detection sensitivity, long ultrasonic time, low peeling off efficiency, and wide application prospect, in simple, rapid and cost effective manner. DETAILED DESCRIPTION - A graphene-modified electrode manufacturing method involves dissolving sample preparation-containing resveratrol in an acidic or neutral buffer solution to obtain a sample solution, using square wave voltammetry, and graphene-modified working electrode to measure resveratrol content in sample solution, where the graphene-modified electrode is produced by mixing 5-4 mg peeling aids and graphite powder in a weight ratio of 2-5:1 by adding stripping solvent ultrasonically for 2-3 hours to obtain graphene dispersion, the peeling aids are gallic acid and sodium hydroxide at a weight ratio of 5:1, followed by polishing glassy carbon electrode to mirror surface, cleaning the electrode surface with nitric acid, ethanol and doubly distilled water ultrasonically for 2min, 2min and 1 min, and secondary drying in an infrared lamp, coating the graphene dispersion liquid uniformly on the dried glass carbon electrode surface, and vacuum-drying, pre-treating the glassy carbon electrode in a buffer solution, and carrying out scan cyclic voltammetry to obtain a finished product.
