Efficient tetracycline hydrochloride degradation via peroxymonosulfate activation by N doped coagulated sludge based biochar: Insights on the nonradical pathway
Researchers found a way to repurpose waste sludge from microplastic removal processes by converting it into a nitrogen-doped carbon material that can break down the antibiotic tetracycline in water. The recycled material performed well across a wide pH range and worked primarily through a nonradical pathway to degrade the antibiotic. The study offers a dual benefit approach that addresses both microplastic waste management and antibiotic contamination in water systems.
