Electrochemical technology has been attracting great attention for treatment of wastewater, as reported in several books and reviews.
It offers many distinctive advantages such as versatility,
high energy efficiency,
safety,
amenability of automation
cost effectiveness because the main reagent is the electron.
However,
traditional electrochemical methods such as electrocoagulation,
electroflotation,
electroflocculation,
electrochemical reduction and electrochlorination can only partially remove persistent organic pollutants (POPs) and/or
produce undesirable and harmful byproducts [16].
Furthermore, the Fenton method is the most popular chemical advanced oxidation process
(AOPs) and has also been successfully used to degrade organic molecules
from wastewater over the past decade .
In a conventional
