Description

technical field

[0001] The invention belongs to the technical field of preparation of photocatalytic electrode materials, and in particular relates to a method for treating antibiotic wastewater by using a visible light responsive semiconductor-MOFs hybrid photocatalytic material electrode. Background technique

[0002] With the continued widespread use of pharmaceuticals and increasing demand for personal care and beauty products, water pollution has gradually become a major environmental concern worldwide. Water pollution caused by antibiotics has become an emerging problem in recent years due to their high solubility, durability, and high toxicity. Antibiotic concentrations of 100 ng L have been reported in untreated domestic sewage -1 to 6 μg L -1 . Sulfa antibiotics are one of the commonly used antibiotics. They are highly toxic to low-concentration bacteria and are prone to resistance to natural populations of bacteria. Therefore, how to effectively treat sulfa anti...
