| Abstract: | A molecularly imprinted polymer membrane modified electrode(PPy/CNT/GCEMIP) was developed via the electrochemical polymerization of pyrrole in the presence of carbon nanotube and the molecular template quercetin(Qu).The electrochemical performance of PPy/CNT/GCEMIP was studied by electrochemical impedance spectroscopy(EIS).The electrochemical behaviors of Qu were investigated with cyclic voltammetry(CV) and differential pulse voltammetry(DPV) at the PPy/CNT/GCEMIP.The results showed that a sensitive oxidati... |
