Accelerated Reduction of Chlorinated Nitroaromatic Antibiotic Chloramphenicol by Biocathode [PDF]
Environmental Science & Technology, 2013 Chlorinated nitroaromatic antibiotic chloramphenicol (CAP) is a priority pollutant in wastewaters. A fed-batch bioelectrochemical system (BES) with biocathode with applied voltage of 0.5 V (served as extracellular electron donor) and glucose as intracellular electron donor was applied to reduce CAP to amine product (AMCl2). The biocathode BES converted

Improved Fe(II) regeneration from actual ferric sludge using a biocathode with granular sludge
, 2023 Ferric sludge pollution and unsustainable utilization of Fe(II) reagent were tough nuts to crack for homogeneous Fenton treatment. Previous Fe(II) regeneration methods are still limited by high reagent consumption or low regeneration rate.
