Degration of TAIC production wastewater by O₃/ACF synergistic catalysis

Triallyl-isocyanurate (TAIC) production wastewater features highly concentrated organic matter that is difficult to degrade, especially when treated by traditional methods. This study analyzed the mechanism of degrading TAIC in wastewater by O₃/ACF synergistic catalysis and investigated the impact of several influential factors, such as ACF dosage, ozone concentration, pH, initial concentration of TAIC, and ACF usage. The results verified the presence of ·OH in the process by a comparative analysis that uses tert-butanol and H₂O₂. The highest removal rate of TAIC was 93.54%, which occurred under the following conditions: ACF dosage of 1.2 g·L^-1, initial TAIC concentration of 200 mg·L^-1, pH of 7.0, ozone concentration of 2 g·h^-1, and reaction time of 40 minutes.
