Voltammetric analysis with the use of a novel electro-polymerised graphene-nafion film modified glassy carbon electrode: Simultaneous analysis of noxious nitroaniline isomers

► Construction of the poly-DHCBAQS/graphene-nafion/GCE. ► Simultaneous analysis of nitroaniline isomers. ► Satisfactory quantitative results were obtained by applying the PCR and PLS methods. ► To provide a new method of constructing electrodes for environmental analysis.
