▎ 摘　　要

NOVELTY - The method involves performing surface polishing operation by a glassy carbon electrode. A circular bottom flask of a glassy carbon electrode is immersed in nitric acid solution for 10-30 hours. A graphite/carbon nano-tube composite material obtaining process is performed. Intensity of the carbon electrode is determined by a hydroquinone intensity detecting system in an electrochemistry working station. A standard working curve is drawn. An electrochemical current detection process is performed to detect hydroquinone concentration and current intensity based on a linear regression equation. USE - Method for calculating hydroquinone trace amount by utilizing a graphene/carbon nano-tube modified electrode. ADVANTAGE - The method enables calculating hydroquinone trace amount in convenient and simple manners and realizing sensitive and selective performance. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view illustrating a hydroquinone trace amount calculating method.'(Drawing includes non-English language text)'
