Abstract :
With di-n-butyl phthalate as the model pollutant and Ru/Al2O3 as catalyst, this paper systemically investigates the removal of DBP in system. Our results have confirmed that Ru/Al2O3 can significantly increase the effect of ozonation. DBP removal in 30 min can reach 96% while only 55% with ozne alone. Efficiency is affected by the ozone dosage, initial concentration of reactants, RuCl3 concentration, catalyst amount, pH value and reaction temperature.
