Sonochemical degradation of ciprofloxacin by hydrogen peroxide and persulfate activated by ultrasound and ferrous ions

Insight into core -shell microporous zinc silicate adsorbent to eliminate antibiotics in aquatic environment under the COVID-19 pandemic

“…Multifarious strategies have been reported previously to effectively remove drugs from wastewater, such as biodegradation (J. J. Li et al, 2022 ), chemical oxidation ( Balarak et al, 2021 ; Kyzas et al, 2022 ), electrochemical treatment ( Ji et al, 2021 ), chemical coagulation ( Gan et al, 2021 ; He et al, 2021 ), and adsorption ( Xu et al, 2022b ; Yilmaz et al, 2022 ). Among these methods, adsorption is the most competitive potential technology for the removal of drugs due to its simplicity, high efficiency, economic advantages and environmental friendliness (Z.…”

Efficient degradation of organic dyes using peroxymonosulfate activated by magnetic graphene oxide

“…Compared to PDS possessing a stable symmetric structure, the activation of asymmetric PMS is easier and stronger oxidation performance to mineralize pollutants is expected. The input of external energy, such as heat, 6 light, 7 ultrasound 8 and electricity 9 can trigger the activation of PMS to produce reactive oxygen species (ROSs) such as sulfate radicals (SO 4 ˙ − ), hydroxyl radicals (˙OH) and singlet oxygen ( 1 O 2 ), which possess strong oxidative ability and promote the degradation of organic pollutants. Besides, catalysts are also extensively employed for PMS activation.…”

Performance and Kinetics of BPA Degradation Initiated by Powdered Iron (or Ferrous Sulfate) and Persulfate in Aqueous Solutions

“…Oxidants (hydrogen peroxide [13], ozone [14], persulfate (PS) [15], and peroxymonosulfate [16]) can be used as precursors to generate free radicals with the help of all kinds of energies or materials [17]. The means of activation can be ultraviolet light (UV) [18], heat [19], microwaves (MW) [20], ultrasound (US) [21], heavy metals (Fe [22], Co [23], Cu [24], Mn [25]), and carbon materials [26,27]. Among the four oxidants mentioned above, PS is favored by researchers because of its stable nature and ease of transport and storage [28].…”
