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.
