Abstract

Abstract: The sensitive detection of honokiol was performed using a graphene nanosheets‐based electrochemical sensor by cyclic voltammogram and a differential pulse anodic stripping voltammogram. Several important parameters such as deposition cycle of reduced graphene oxide, the acidity of the running buffer, accumulation potential and accumulation time were investigated to acquire the optimum conditions. The sensor was further applied to quantification of honokiol in the concentration range from 0.005 to 10 µM with a low detection limit of 1.7 nM. Finally, the sensor successfully determined the content of honokiol in Ageratum Liquid with a satisfied recovery of 98.2 %∼99.1 %. Abstract :
