| Abstract: |
| An electrochemical method was developed for the detection of hesperetin(HSP) using a three dimensional potassium sorbate derived interconnected porous carbon(PSIPC) modified electrode.The PSIPC material was synthesized by pyrolyzing method,using organic salt potassium sorbate(PS) as template via heating treatment in nitrogen atmosphere,and was characterized by scanning electron microscopy(SEM),transmission electron microscopy(TEM),X ray powder diffraction(XRD),X photoelectron spectroscopy(XPS),thermogravimetric analysis(TGA) and N2 adsorption and desorption tests.PSIPC-700,PSIPC-800 and PSIPC-900 obtained in different temperatures were directly dropped onto the surface of a glassy carbon electrode to obtain PSIPC modified electrodes(PSIPC-700/GCE,PSIPC-800/GCE and PSIPC-900/GCE).The electrochemical behaviors of HSP on PSIPC-900/GCE were investigated by cyclic voltammetry(CV) and differential pulse voltammetry(DPV).Under the optimized conditions,the linear range for HSP was in the range of 0.05-15.0 μmol/L.The limit of detection was as low as 0.021 μmol/L.With high sensitivity and wide detection range,this method could be applied in the detection of HSP in real samples. |
