- Abstract
- In this study, ibuprofen(IBP) degradation by the photochemical (UV/S2O82-) and sonochemical (US/S2O82-) processes was examined under various parameters, such as UV (10~40±5 W/L) and US (50~90±5 W/L) power density, optimum dosage of persulfate ion (S2O82-), temperature (20~60℃) and anions effect (Cl-, HCO3-, CO32-). The pseudo‐first‐order degradation rate constants were in the order of 10-1 to 10-5 min-1 depending on each processes. The synergistic effect of IBP degradation in UV/S2O82- and US/S2O82- processes could investigated, due to the generation of SO4- radical. This result can confirm from the produced H2O2 and SO42- concentration in each processes. IBP degradation rate affected by the S2O82- dosage, temperature, power and anion existence parameters. In particular, IBP degradation rate increased with the increase of the temperature (60℃) and applied power density (UV:40±5 W/L, US:90±5 W/L). On the other hand, anions effect on the IBP degradation was negative, due to the anion play as a the scavenger of radical.
