Electrochemical Analysis of 2-chlorophenol Using a MultiWalled Carbon Nanotube-Ionic Liquid Composite Modified Electrode

Abstract

A multi-walled carbon nanotube-ionic liquid composite modified glassy carbon electrode was fabricated. The modified electrode showed highly catalytic ability towards the oxidation of 2- chlorophenol. Square wave voltammetry was used for the determination of 2-chlorophenol. The oxidation peak currents were linearly with the concentrations of 2-chlorophenol in the range of 0.5 to 12.0 μM, with a detection limit of 0.1 μM. The proposed method was successfully applied for the determination of 2-chlorophenol in water samples with satisfactory recoveries.
