Sonochemical Degradation of Phenol in Dilute Aqueous Solutions: Comparison of the Reaction Rates at 20 and 487 kHz
Christian Pétrier,Marie-Francoise Lamy,Anne Francony,Abdallah Benahcene,Bernard David,Viviane Renaudin,Nicolas Gondrexon +6 more
Journal ArticleDOI
Unexpected frequency effects on the rate of oxidative processes induced by ultrasound
TL;DR: Evidence is given that in the presence of argon or oxygen these oxidative processes occur in enhanced yields when a high frequency is used in comparison with the more commonly used low frequency.
Journal ArticleDOI
Ultrasonic treatment of water contaminated with ibuprofen.
Fabiola Méndez-Arriaga,Ricardo A. Torres-Palma,Ricardo A. Torres-Palma,Ricardo A. Torres-Palma,Christian Pétrier,Santiago Esplugas,Jaime Giménez,Cesar Pulgarin +7 more
TL;DR: Applied US power, dissolved gas, pH and initial concentration of IBP were the parameters investigated under sonication (300 kHz), indicating that the process oxidize the ibuprofen compound to biodegradable substances removable in a subsequent biological step.
Journal ArticleDOI
Allylzinc reagents additions in aqueous media
TL;DR: Ou et al. as mentioned in this paper propose attention d'alcools homoallyliques lorsque des halogenures d'allyle, zinc et aldehydes ou cetones sont soumis a reaction sonochimique.
Journal ArticleDOI
Ultrasonic waste-water treatment: incidence of ultrasonic frequency on the rate of phenol and carbon tetrachloride degradation.
Christian Pétrier,Anne Francony +1 more
TL;DR: It is shown that the rates of reactions involving hydroxyl radicals (hydrogen peroxide formation and phenol degradation) have a maximum value at 200 kHz, which may be the result of better HO radicals availability outside of the bubble of cavitation.
