Bamboo Fungus-Derived Porous Nitrogen-Doped Carbon for the Fast, Sensitive Determination of Bisphenol A
Biomass-derived carbon materials have been considered as perfect substitutes for the traditional doped carbon materials, owing to its simple synthesis, rich-doped hetero-atoms, low cost and satisfactory electrochemical properties. In this paper, a rich nitrogendoped carbon (NDC) material derived from bamboo fungus by simple carbonization was firstly applied for the electrochemical determination of Bisphenol A (BPA). NDC showed high catalytic activity towards the BPA oxidation for its rich doped nitrogen, high conductivity and porous structure. The morphology and structure features of NDC were characterized by the transmission electron microscopes and Raman spectrum. Meanwhile, the electrochemical properties of NDC modified glassy carbon electrode (GCE) and the behaviors of BPA on the NDC modified GCE (NDC/GCE) were estimated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Under the optimum conditions, differential pulse voltammetry (DPV) was used for the quantitative determination of BPA. A low detection limit (LOD) of 1.068 mu M (IUPAC S/N = 3) was obtained within the range of 1.0 mu M to 50.0 mu M. And the NDC/GCE was further applied for the practical determination of BPA in soil extract samples successfully. The results revealed that the simple and sensitive NDC based platform could be a potential approach for the practical detection of BPA. (C) The Author(s) 2016. Published by ECS.
