Electroanalysis of nicotine at an electroreduced carboxylated graphene modified glassy carbon electrodeElectronic supplementary information (ESI) available. See DOI: 10.1039/c4ay01872a
A carboxylated graphene (CG) modified glassy carbon electrode (GCE) was prepared by cast-coating a CG solution on a GCE surface, for quantitative analysis of nicotine based on cyclic voltammetry after potentiostatic enrichment of nicotine at −1.1 V for 240 s in 0.1 M KH 2 PO 4 -Na 2 HPO 4 buffer sol...
