Development and Application of Different Non-thermal Plasma Reactors for the Removal of Perfluorosurfactants in Water: A Comparative Study

Efficient activation of persulfate by calcium sulfate whisker supported nanoscale zero-valent iron for methyl orange removal

“…This decrease could be attributed to the scavenging of radicals induced by the excessive generation of SO 4 c À . Increasing PS concentrations beyond a quantitative value would induce slow degradation rates, as indicated in eqn (7) and (8). 46,47 Hence, 4 mM was considered to be the optimal PS concentration in the present study.…”

“…Typical AOPs include ozonation, 1 Fenton, photooxidation, 2 electrochemical oxidation, [3][4][5] non-thermal plasma, 6,7 Persulfate (PS) advanced oxidation 8 and combinations of these technologies. PS has recently gained considerable attention because of its high efficiency for the mineralization and degradation of refractory organic contaminants in water and soil.…”

Hazardous wastes treatment technologies

“…As affectedbyoperational parameters, such as feed gas type, gas flow rate, water flow rate, and power. Mahyar et al (2019) reported the treatment of perfluorosurfactants (PFS), and PFOS in dielectric barrier discharge (DBD) and nano-pulse corona discharge (PCD) reactors. The efficiency of PFS degradation by ozonation and photocatalytic ozonation processes were also compared.…”

Application of Photocatalytic Falling Film Reactor to Elucidate the Degradation Pathways of Pharmaceutical Diclofenac and Ibuprofen in Aqueous Solutions

“…AOPs are considered to be an effective and promising method for the degradation and mineralization of aqueous recalcitrant pharmaceutical compounds [2]. Different AOPs and their combinations have been compared and investigated for the removal of chloroacetic acids from aqueous solutions, using the design of a planar falling film reactor [14] The same design of reactor have been applied for the removal of perfuorosurfactants through non-thermal plasma generated in a dielectric barrier discharge [18]. In order to mitigate the risks of these pollutants in a water environment, various AOPs have been examined for DCF and IBP removal [10].…”
