摘要：

In this paper, the gold nanoparticles/L-cysteine functionalized graphene oxide (AuNPs/GO-SH) nanocomposites was synthetized with a simple approach for nitrite determination. The prepared nanocomposites were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction and Raman spectroscopy, etc. A pair of well-defined redox peaks was founded for AuNPs/GO-SH hybrids with a formal potential of 0.90 V in 0.1M phosphate buffered solution by cyclic voltammetry. Under optimal conditions, the sensor could detect nitrite as low as 0.25 mu M with a wide linear response range from 5 to 1000 mu M, high sensitivity and excellent selectivity. The superior results of nitrite determination in pickled radish showed a promising application for determination of nitrite in food. (C) 2018 Elsevier B.V. All rights reserved.
