ClearPromoting Degradation of Polyamide-Microplastic Fibers Using Hydroxy Radical Generated by Electrochemical Advanced Oxidation Processes
Researchers demonstrated that hydroxyl radicals generated through electrochemical processes can degrade polyamide (nylon) microplastic fibers significantly faster than biological methods — reducing fiber diameter by nearly 14% and toughness by almost 79% within 12 hours. Chemical analysis confirmed that the hydroxyl radicals cleave the amide bonds in nylon, breaking the polymer into shorter compounds. This offers a promising wastewater treatment approach for removing synthetic microfibers released during textile washing, which currently pass through conventional sewage treatment plants largely intact.
