▎ 摘　　要

NOVELTY - The method involves forming a modified electrode as a beta-manganese oxide nano graphene modified electrode. A graphene oxide electrode is attached on a glassy carbon electrode or gold electrode. The graphene oxide electrode is formed. Graphene oxide is reduced to obtain the graphene modified electrode by electrochemical process. Depositing process of nanometre Nickel oxide is performed to form the beta-manganese oxide nano graphene modified electrode. Pre-treating of bare electrode, glassy carbon electrode or gold electrode grinding, polishing and washing is performed. USE - Method for simultaneously detecting a modified electrode of hydroquinone and pyrocatechol in a water sample. ADVANTAGE - The method enables ensuring high stability and reproduction quality, and improving measuring effect of phenol of environmental pollution in water sample. DESCRIPTION OF DRAWING(S) - The drawing shows a graph view illustrating a method for simultaneously detecting a modified electrode of hydroquinone and pyrocatechol in a water sample.
