Evaluation of persulfate oxidative wet scrubber for removing BTEX gases

Kinetic study of diuron oxidation and mineralization by persulphate: Effects of temperature, oxidant concentration and iron dosage method

“…In agreement with these results, the importance of the way of adding iron in enhancing destruction of contaminants in the iron activated persulphate system is also widely reported [15,20,[23][24][25].…”

Degradation of p-chloroaniline by persulfate activated with ferrous sulfide ore particles

“…Moreover, the breakdown of PS also produced sulfate free radicals as descripted in Eqs. (19) and (20). However, with the continue increase of the PS concentration, a large number of SO 4 ÀÅ was produced instantly, which reacted with each other and consumed according to Eq.…”

“…And it can be produced from persulfate (PS) through photochemical, thermal, radiolytic, or redox decomposition [Reactions (1)-(4)] [16]. Persulfate oxidation has been applied to degrade various contaminants, such as Azo dye acid orange 7 [17], PCBs [18], gasoline or petroleum components [19][20], chlorophenols [16,21], and bisphenol A [22]. Transition metals such as Co, Ag, Cu, Fe have certain activation ability on PS for pollutants degradation at normal temperature and pressure.…”

Evaluation of activated carbon for remediating benzene contamination: Adsorption and oxidative regeneration

“…ISCO using persulfate and activated persulfate has emerged as a viable remediation technology for the treatment of subsurface contaminants. Persulfate activation, an advanced oxidation process (AOP), to generate sulfate radicals (SO 4 −• ) has been demonstrated as an effective means of destroying aromatic organics such as benzene, toluene, ethyl benzene and xylene [12][13][14]. Persulfate activation using heat (e.g., 30-99 • C) and the presence of transitional metals (e.g., Fe 2+ ) can generate SO 4 −• in accordance with Eqs.…”
