  Nonylphenol ethoxylate (NPE 10) is a non ionic surfactant which is
synthesized from alkylphenol ethoxylate. The accumulation of NPE-10 in
wastewater will endanger the ecosystem as well as human being. At present, by
an advancement of technology NPE 10 can be degraded indirectly by using an
electrochemically treatment. Thus, this study aimed to evaluate the potential
electrodegradation of NPE 10 by mediated electrochemical oxidation (MEO) using
Ce(IV) ionic mediator. In addition, the influence of Ag(I) ionic catalyst in
the performance of MEO for degradation of NPE 10 was also observed. The potency
of MEO technology in degradation NPE 10 was evaluated by voltammetry technique
and confirmed by titrimetry and LC-MS analyses. The results showed that in the
absence of Ag(I) ionic catalyst, the degradation of NPE 10 by MEO was 85.93 %.
Furthermore, when the Ag(I) ionic catalyst was applied, the performance of MEO
in degradation of NPE 10 was improved to 95.12 %. The back titration using
Ba(OH)2 confirmed the formation of CO2 by 46.79 %. Whereas the redox titration
shows the total of degradation organic compounds by 42.50 %, which was
emphasized by formation of two new peaks in LC-MS chromatogram. In summary, our
results confirm the potential of MEO technology for NPE-10 degradation.
