The graphene-chitosan composite film modified glassy carbon electrode (GR-CS/GCE) was prepared for the simultaneous detection of p-nitrophenol (p-NP) and o-nitrophenol (o-NP). GR-CS/GCE showed good electrocatalytic activity for the reduction of p-NP and o-NP. Under the optimized detection conditions, p-NP exhibited a linear detection range of 0.1 similar to 140 mu M with the detection limit (S/N = 3) of 0.09 mu M at GR-CS/GCE, while 1 similar to 240 mu M for o-NP with a detection limit of 0.1 mu M. The OR-CS demonstrated as a promising sensor material for the simultaneous detection of nitrophenol isomers. (C) 2015 The Electrochemical Society. All rights reserved.
