Elektroperokson
(E-perokson) prosesi, ozon ve elektrooksidasyon proseslerini bir arada
bulunduran bir ileri oksidasyon yöntemidir. 
E-perokson prosesi, oksijenden ozon üretiminde jeneratörün dönüşüm
veriminin düşük olmasından faydalanarak, enerji kaybı olarak sisteme verilen
oksijeni, karbon bazlı katotta indirgeyerek hidrojen perokside dönüştürür. Hidrojen
peroksidin sonrasında ozon ile reaksiyona girerek OH• radikalleri oluşturması
nedeniyle E-perokson, yüksek oksidasyon özelliğine sahip proses şartları
sağlar.  Ancak, tannik asidin düşük pH’ya
ve ozon reaktif aromatik yapıya sahip karakteristik özellikleri sebebi ile
E-perokson prosesinin daha fazla OH• radikali oluşturma üstünlüğü, tannik asit
oksidasyonu şartlarında elde edilememiştir. Ozonlama sisteminin E-peroksona
dönüştürülmesiyle %10 daha fazla çözünmüş organik karbon mineralizasyonu sağlanmıştır.
Tannik asidin oksidasyonunda H₂O₂ doğrudan görev
almazken, reaksiyon başlarında moleküler ozon reaksiyonu domine etmiştir. Ozona
daha az reaktif karboksilik asitlerin oluşmasıyla, oksidasyon OH• radikalleri
tarafından yönetilmiş ve sözü edilen verim artışı sağlanmıştır.

Tannic acid oxidation by electroperoxone

Öz

The electro-peroxone (E-peroxone) process as an
advanced oxidation process integrates ozonation and electrooxidation processes
in a system. E-peroxone process produces in situ H₂O₂ from the excessive
oxygen during ozone generation. E-peroxone provides a highly oxidative reaction
conditions due to further reaction of H₂O₂ with ozone to produce OH• radicals. Since tannic acid has low pH and
ozone-reactive aromatic content as its characteristic behavior, the superiority of the E-peroxone process to form more OH•
radicals has not been achieved under tannic acid oxidation conditions. By
converting the ozonation system to E-peroxone, 10% more dissolved organic
carbon mineralization was provided. While H₂O₂ did not
directly involved in the oxidation of tannic acid, the molecular ozone reaction
dominates the oxidation at the beginning of the reaction. With the formation of
less ozone-reactive structures (i.e. carboxylic acids), the oxidation is directed
by the OH• radicals and the mentioned efficiency was provided in E-peroxone
process.
