Abstract
A group of carbon-based electrodes, i.e., glassy-carbon (GC), boron doped
diamond (BDD), expanded graphite-polystyrene composite (EG-PS), expanded
graphite-epoxy composite (EG-Epoxy) and expanded graphite-carbon nanofiberepoxy
composite (EG-CNF-Epoxy) electrodes were investigated for
electrochemical degradation of 4-chlorophenol (4-CP). Based on the investigated
electrochemical techniques, e.g., cyclic voltammetry (CV) and
chronoamperometry (CA), the operation conditions and the electrode suitable for
electrochemical oxidation of 4-CP were selected. In addition, multiple pulsed
amperometry (MPA) was applied for the in-situ electrochemical cleaning of the
electrode surface to improve the electrode efficiency. The BDD electrode
exhibited the best features related to the 4-CP electrochemical degradation
efficiency.
Keywords: wastewater, electrochemical degradation, 4-CP, carbon-based
anodes.
1 Introduction
The phenol derivates are toxic and non-biodegradable organic compounds
included in the list of priority phenols, which are used/produced in several
industrial processes, being commonly used as preservatives, disinfectants, in
pulp processing, in the manufacture of pesticides and intermediars [1–4].
The choice of wastewater treatment method depends on the treatment
performance and economic component. Due to the treatment of industrial
