Activation of peracetic acid by electrodes using biogenic electrons: A novel energy- and catalyst-free process to eliminate pharmaceuticals

•A novel approach for energy- and catalyst-free activation of peracetic acid (PAA).•Bioelectrochemical activation of PAA yielded •OH at a 3:1 ratio to CH3C(O)O•.••OH, CH3C(O)O• reacting with PAA to form CH3C(O)OO• contributes 68.1 % SMX removal.•The transformation byproducts of SMX and their toxicit...
