چکیده
|
Trans-resveratrol is often considered as one of the quality standards of red wine,and the development of a sensitive and reliable method for monitoring the trans-resveratrol levels in red wine is an urgent requirement for the quality control. here,a novel voltammetric approach was described for probing trans-resveratrol using a graphene-modified glassy carbon (gc) electrode. the proposed electrode was prepared by one-step electrodeposition of reduced graphene oxide (ergo) at a gc electrode. compared with the bare gc electrode,the introduced graphene film on the electrode surface dramatically improved the sensitivity of the sensor response due to the π-π interaction between the graphene and trans-resveratrol. the developed sensor exhibited low detection limit of 0.2 μm with wide linear range of 0.8-32 μm and high stability. for the analysis of trans-resveratrol in red wine,the high anti-interference ability and the good recoveries indicated the great potential for practical applications. © 2017 lantao liu et al.
