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.
