© 2018 The Authors. Herein, we present an amperometric sensor for hydrazine developed via simple potentiodynamic electrochemical polymerization of O-Toluidine Blue (pTBO) on functionalized multi walled carbon nanotubes (f-MWCNTs) coated glassy carbon electrode (GCE). The obtained of f-MWCNTs/pTBO composite was confirmed through FESEM, EDX and cyclic voltammetric studies. Relative to pTBO modified electrodes, f-MWCNTs/pTBO modified GCE displayed a well-defined electro-oxidation peak current response towards the detection of hydrazine. f-MWCNTs/pTBO/GCE exposes its good electrocatalytic ability in a wide linear range from 1 μM to 357 μM. Our modified electrode also possesses low limits of detection (0.24 μM) with high sensitivity (2492 μA mM -1 cm -2 ) value. The successful demonstration of feasible practicality of f-MWCNTs/pTBO composite modified GCE was performed in untreated rain, lake and tap water samples.
