Summary:In order to well use waste biomass and realise the quantitative analysis of luteolin, the sorghum straw from the old broom was used to prepare biomass carbon material (CMS-PCSS) through the molten salt carbonization. Then the CMS-PCSS was characterised by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) Raman spectra (Raman), and N2 sorption analysis. In addition, the electrochemical performance of the CMS-PCSS based sensors was examined by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). Under the first-rank experimental conditions, the electrochemical sensor established with this material performed well in the quantitative analysis and actual sample detection of luteolin, the detection range of luteolin was 0.05~10.0 μmol/L, and the actual achievable minimum detection limit was 0.019 μmol/L.
