Abatement kinetics of highly concentrated 1H-Benzotriazole in aqueous solution by ozonation
چکیده انگلیسی
In this work, we investigated the abatement of highly concentrated 1H-Benzotriazole (BTA) in aqueous solution by ozonation. Focusing on the COD removal and BTA degradation, the effects of different operational factors were explored, including different initial BTA concentrations (100-1000 mg/L), ozone dosages (16-48 mg/min) and initial pH values (3-11). It was found that the degradation of BTA was obviously affected by the initial concentration of BTA, pH value and O3 dosage. And the optimized pH value was observed at 11. The increasing of ozone dosage and the pH value would accelerate the degradation efficiency of BTA and COD removal, while the increasing of initial BTA concentration would hamper this process. Based on the effects of ozone dosage, initial BTA concentration and initial pH value, a kinetic model was established with the function of C = C0exp(−8.68QO32.4997C0−2.1262[OH−]0.0444t).
