Abstract

The electrooxidation, at different pH values, of several chlorophenols on porous electrodes obtained by painting commercial glassy carbon (GC) electrodes with a suspension of graphite powder and an iron oxide-covered aluminosilicate (AlSiFe) has been studied. Samples of the AlSiFe suspension were characterized by electrophoretic migration, and the dried powder was analysed by FTIR and XPS spectroscopy. The conductivity of the modified GC electrode was corroborated by cyclic voltammetry of the ferro-ferricyanide couple. The influence of the chlorophenol structure on the reactivity of the phenols was studied.
