摘要

beta-Cyclodextrin functionalized reduced graphene oxide (beta-CD/RGO) was successfully prepared using a simple wet chemical method. The beta-CD/RGO nanohybrid was characterized by UV-vis spectroscopy, FTIR, Raman spectroscopy, TEM and SEM. The results confirmed that beta-CD had effectively covered the RGO surface. The beta-CD/RGO nanohybrid modified glassy carbon electrode was employed for the sensitive electrochemical determination of paracetamol. Cyclic voltammetry measurements indicated that beta-CD/RGO could significantly enhance the electrochemical response of paracetamol due to the outstanding electronic properties of RGO sheets and the high supramolecular recognition and enrichment capability of beta-CD. The experimental factors were investigated and optimized. Under optimized conditions, the amperometric oxidation currents of paracetamol were linearly proportional to the concentration in the range of 0.01 to 0.8 mM with a detection limit of 2.3 mu M (S/N = 3). Furthermore, the proposed sensor exhibited an excellent anti-interference property and acceptable reproducibility.
