摘要：

In this paper, we demonstrate that Au-reduced graphene oxide/PDDA nanocomposites (Au-RGO/PDDA) can be rapidly synthesized through a facile, cost-effective, one-pot method with the use of poly (diallydimethylammonium chloride) (PDDA) as both reducing and stabilizing agents. The prepared AuRGO/ PDDA nanocomposites film endowed the modified electrode fast electron transfer rate and high electrocatalytic activity toward nitrite oxidation. Under the optimal conditions, the oxidation current increased linearly with increasing the concentration of nitrite in the range 0.05-8.5 mu M with the correlation coefficient of 0.9964 and the detection limit of 0.04 mu M at a ratio of signal to noise of 3 using differential pulse voltammograms (DPV). The presented sensor was also demonstrated for the determination of nitrite ion in lake water, meat and dairy products samples with satisfactory results. (C) 2014 Elsevier B.V. All rights reserved.
