Journal ArticleDOI
Manipulation of persistent free radicals in biochar to activate persulfate for contaminant degradation.
TL;DR: It was found that both the concentration and type of PFRs were the dominant factors controlling the activation of persulfate by biochar and that superoxide radical anions account for 20-30% of sulfate radical generation in biochar/persulfate.
Journal ArticleDOI
Activation of persulfate by quinones: free radical reactions and implication for the degradation of PCBs.
TL;DR: The findings of this study elucidated a new pathway of persulfate activation, which could degrade environmental contaminants efficiently and provide useful information for the remediation of contaminated soil and water by Persulfate.
Journal ArticleDOI
Key Role of Persistent Free Radicals in Hydrogen Peroxide Activation by Biochar: Implications to Organic Contaminant Degradation
TL;DR: It was found that H2O2 can be effectively activated by biochar, which produces hydroxyl radical ((•)OH) to degrade 2-CB and the activation mechanism was elucidated by electron paramagnetic resonance (EPR) and salicylic acid (SA) trapping techniques.
Journal ArticleDOI
Superoxide radical driving the activation of persulfate by magnetite nanoparticles: Implications for the degradation of PCBs
TL;DR: In this article, the activation of persulfate (PS) by magnetite nanoparticles for the degradation of 2,4,4′-CB (PCB28), a selected model compound, and the underlying mechanism was elucidated.
Journal ArticleDOI
Sulfate radical-based degradation of polychlorinated biphenyls: effects of chloride ion and reaction kinetics.
TL;DR: Investigation of the effect of chloride ion on the degradation of 2,4,4'-CB (PCB28) and biphenyl (BP) by persulfate, based on the produced SO(4)(·-) showed that chloride ion could influence the selectivity of radical species and their distribution, and increase the concentration of the sum ofradical species.
