Elektroperokson prosesi ile tannik asit oksidasyonu

Abstract

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 H 2 O 2 f rom the excessive oxygen during ozone generation. E-peroxone provides a highly oxidative reaction conditions due to further reaction of H 2 O 2 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 H 2 O 2 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.
