Description

technical field

[0001] The invention belongs to the field of visible light catalysis, and relates to a method for treating organic pollutants and photocatalytic sterilization by using modified carbon quantum dots to load hollow tubular carbon nitride photocatalysts. Background technique

[0002] The rapid growth of population and the rapid development of economy have led to an increasing demand for water resources. The resulting water pollution is a worldwide problem. Among them, the pollution of organic pollutants to the water environment has been widely concerned. , such as antibiotic wastewater as refractory wastewater, has been a research hotspot. Antibiotics are widely used in medicine and aquaculture because of their antibacterial, antifungal, antiviral, and antiparasitic properties. Tetracycline (TC), as a kind of antibiotic, is regarded as an essential drug by the World Health Organization (WHO). However, TC metabolism in animals is poor, resulting in a large amoun...
