Abstract
The electrochemical oxidation of 2,4-dichlorophenol (2,4-DCP) at a glassy carbon (GC) electrode modified with Nickel phthalocyanine (NiPc), a complex of nickel without any substitutents, was studied by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques. The modification of the electrode was performed by repetitive cyclic voltammetric scans in NiPc solution. The number of optimum cycles was obtained 70. Nickel phthalocyanine with different thickness was characterised by electrochemical impedance spectroscopy and it was corresponding to cyclic voltammograms. Also the catalytic activity of the modified electrode (GC/NiPc) was investigated. It was found that, GC/NiPc electrode had significant response for 2,4-DCP oxidation. Therefore, it can be a good candidate for electrooxidation of 2,4-DCP. By using this technique the small amounts of DCP compound in waste waters can be detected
