摘要：
In this study, surface-functionalized nitrogen-doped graphene was prepared with 1, 3, 6, 8-pyrenetetrasulfonic acid tetrasodium salt in a simple way. The characteristics of the material were demonstrated by UV-vis absorption spectra, X-ray photoelectron spectroscopy, and electrochemical experiments. Then, the glassy carbon electrode was modified by the functionalized nitrogen-doped graphene and hexadecyltrimethylammonium bromide for tetrabromobisphenol A (TBBPA) determination. The oxidation current response of TBBPA was enhanced at the modified electrode and the mechanism was investigated. Upon the optimization of assay parameters, including pH value, accumulation potential and time, the oxidation current was linearly related to the concentration of TBBPA in the range of 0.01-1 mu M with a detection limit of 9 nM. Moreover, the modified electrode was applied to detect TBBPA in water samples with simple, low cost, and high efficiency. (C) 2016 Elsevier B.V. All rights reserved.
