Abstract


In this study, the voltammetric behavior of 4-nitrophenol, 2,4-nitrophenol and 2,4,6-tri nitro phenol in acidic medium was investigated by cyclic voltammetry at glassy carbon electrode.The reduction of the para nitro phenol (2.10-4M) in the presence of HCL (0.5M) as supporting electrolyte reveals one irreversible peak while the reduction of the 2,4-di nitro phenol shows two irreversible current peaks and the reduction of the 2,4,6- tri nitro phenol gives three irreversible current peaks to produce the derivatives amines as the final products

Keywords: Polarography, Cyclic voltammetry, Glassy carbon electrode (GCE), 4-nitro phenol, 2,4-di nitro phenol , 2,4,6 tri nitro phenol
