Ultrasonic power improvement of flumequine degradation effectiveness in aqueous solution via direct and indirect action of mechanical acoustic wave

Abstract

The current research work aimed to describe the roles of ultrasonic power under sono-Fenton process in the degradation of flumequine (FLU) in water. For this purpose, the effects of some parameters including temperature, ferrous ion concentration, chemical oxidant concentration (SO and Cl) and the initial pH value of the reaction kinetics were investigated. Results showed that the degradation of FLU antibiotic was accelerated by ultrasonic irradiation and the presence of an inorganic oxidant. The sono-generation of active species such as hydroxyl radicals (HO and HOO) and sulfate radicals (SO) as strong oxidizing agents improved the FLU degradation. In fact, the peroxydisulfate anion (SO) has been identified as among parameters that enhanced the degradation process. Under optimal conditions, 98% of the flumequine removal was carried out within 80 min at 60 °C.

Kinetics and mechanisms of flumequine degradation by sulfate radical based AOP in different water samples containing inorganic anions

“… 8 Harrabi et al found that the degradation of FLU was improved by the presence of hydroxyl radicals and sulfate radicals. 9 A study indicated that the effective removal of flumequine by combined UV/ClO 2 advanced oxidation processes (AOPs). 10 Solis et al found that the enhanced elimination of flumequine in the presence of peroxymonosulfate (PMS) and magnetic graphene catalysts.…”

Towards synergistic combination of biochar/ultrasonic persulfate enhancing removal of natural humic acids from water

“…The removal of HAs is unfavorable when the concentration of persulfate exceeds a certain range [34,35]. In addition, it has been reported that the number of cavitation bubbles per unit volume in the ultrasonic oxidation system decreases at higher viscosity, which would induce cavitation [36]. Fig.…”

Removal of Ciprofloxacin from Wastewater by Ultrasound/Electric Field/Sodium Persulfate (US/E/PS)

“…Sometimes it is even necessary to use other water treatment methods to achieve better performance and efficiency. As a new star of water treatment technology that has arisen in the past 30 years, advanced oxidation technology has been noticed by workers in the field of water treatment research throughout the world [27]. The treatment of high-concentration organic wastewater and micro-polluted organic matter in the water body by advanced oxidation technology has also become a hot research topic [28,29].…”
