Electrochemical Reduction Behavior of m-Nitrophenol on GC Electrode in Ionic Liquid [EMIM]Br

Abstract

Abstract: The direct electrochemical reduction of m-nitrophenol on GC electrode was investigated in ionic liquid(IL), 1-ethyl-3-methylimidazolium bromide([EMIM]Br) by using cyclic voltammetry and chronocoulometry. The diffusion coefficient D of m-nitrophenol in [EMIM]Br was 9.184×10^-7 cm²/s, while the transfer coefficient was 0.37. It can be proved that the reduction of m-nitrophenol on GC electrode was an irreversible process and the electrode reaction was diffusion-controlled by cyclic voltammetry.

Key words: 1-Ethyl-3-methylimidazolium bromide([EMIM]Br), Cyclic voltammetry, Chronocoulometry, m-Nitrophenol
