摘要：Ibuprofen (IBP) is a widely used analgesic and anti-inflammatory drug, found as a pollutant in aqueous environments. Sonochemistry offers a new alternative against persistent water organic-pollutants. The aim of this paper is to evaluate the influence of several parameters on degradation of IBP in water solutions (in air saturated): the power of the ultrasonic process, the pH of the solution, the initial concentration of the pollutant. Moreover, the effects of photo irradiation and the combination of both treatments (UV US) were studied. A higher degradation was observed in lower initial concentration of IBP, while a higher power increased the initial rate of IBP degradation. When sonophotolysis was applied (at a wavelength of 254 nm and ultrasonic power of 80 W), a significant enhancement in the degradation of IBP (99.6 % in 10 min) was observed. Otherwise, elimination of total organic carbon (TOC) was investigated.
