UVA-LED assisted persulfate/nZVI and hydrogen peroxide/nZVI for degrading 4-chlorophenol in aqueous solutions

Removalof Cephalexin From Aqueous Solutions Using Magnesium Oxide/Granular Activated Carbon Hybrid Photocatalytic Process

“…where %, C 0 , and C t represent the percent of CLX removal, initial concentration, and final concentration after different times, respectively (34). Two kinetic models (i.e., first-and second-order types) were used to determine the kinetics coefficients (21).…”

“…The use of UV irradiation, along with oxidants including hydrogen peroxide (18), ozone (19), and persulfate (20) could be effective for improving the function of oxidation processes. Previous research has evaluated the photodegradation of antibiotics by direct absorption of UV irradiation (21) and combined UV/hydrogen peroxide, UV/periodate, and the like (22). Recently, the application of the photocatalytic process, in which a catalyst is exposed to UV irradiation to generate hydroxyl radicals (OHº), has been widely considered due to its costeffectiveness and high efficiency (23).…”

Degradation of phenol using US/Periodate/nZVI system from aqueous solutions

“…Physico-chemical techniques are usually needed after treatment or disposal of produced sludge (Alavi et al, 2018;Baziar et al, 2018b). In the last few decades, applications of AOPs in the aqueous solution have been increasingly used because of their good performance to degrade a broad range of persistent organic pollutants (Seidmohammadi et al, 2016;Seid-Mohamadi et al, 2015;Seidmohammadi et al, 2018;Naghan et al, 2015). The performance of AOPs are underlying the production of strong reactive intermediates, e.g.…”
