Reduced graphene oxide enhances emerging contaminants removal in anaerobic wastewater treatment
The biotransformation pathways of some ECs were activated after the addition of rGO, ultimately leading to their transformation into metabolic intermediates capable of entering the tricarboxylic acid (TCA) cycle. The enhanced syntrophic metabolism, along with the increased abundance of ECs-biotransforming microorganisms and enzymes, collectively confirmed that the addition of rGO provided additional metabolic pathways for ECs removal.
