Removal of tetracycline from aqueous solution by ultrasound and ultraviolet enhanced persulfate oxidation

Treatment of cefixime-containing wastewater using ultrasound, H2O2, and sodium persulfate and antimicrobial analysis

“…A lower requirement of oxidants indicates that a higher concentration of oxidizing radicals is produced for the removal of cefixime but not sufficient for complete or enhanced removal of cefixime. It may be due to a) recombination of formed radicals to scavenging radicals and b) formed radicals may be utilized for the further mineralization of cefixime (Almasi et al 2020;Mahdi-Ahmed and Chiron, 2014;Seid-Mohammadi et al 2019;Malakootian and Asadzadeh, 2020). Detailed mechanism for radical formation is given by Eq.…”

“…Removal of such low-level concentrations of antibiotics is challenging. There are many studies on the photodegradation of cefixime available in the literature and most of the work is limited to analysis of the potential effect of synthesis material for removal of cefixime (Almasi et al 2020;Mahdi-Ahmed and Chiron, 2020;Seid-Mohammadi et al 2019;Malakootian and Asadzadeh, 2020). One of the shortfalls associated with the photodegradation method is the fast recombination of formed radicals which reduces the overall efficiency of the process (Malakootian and Asadzadeh, 2020;Chakraborty and Abraham, 2017;Lee and Kim, 2023).…”

Other investigations on the removal of cefixime are available on the conventional approach with inherent limitation of regeneration of catalyst and disposal of secondary solid waste generated during the process (Lee and Kim, 2023;Anandan et al, 2020;Li et al 2017).…”

“…A review on sonochemical degradation of antibiotics has been reported, and clear guidelines for future work. It suggested that more investigations are required on sonochemical antibiotic degradation to understand the combined effects of radical promoters with sonochemical effects (Malakootian and Asadzadeh, 2020).…”

Preparation of a silver ferrite-assisted tungsten oxide nanocomposite for efficient sonocatalytic degradation of organic pollutants activated by PMS followed by toxicity evaluation

“…The generated radicals are highly efficient in the degradation process and the lifetime of the ˙SO 4 2− radicals is higher than that of the ˙OH radicals. 15,16 The PMS is usually activated by UV light irradiation, metal free catalysts, transition metals and sonication processes. 17,18…”
