Description

technical field

[0001] The invention belongs to the technical field of sewage treatment, and relates to a method for catalytically removing antibiotics by using carbon nitride / nitrogen doped hollow mesoporous carbon / bismuth trioxide ternary Z-type photocatalyst, in particular to a method for using carbon nitride / nitrogen doped Hollow mesoporous carbon / bismuth trioxide ternary Z-type photocatalyst for catalytic removal of antibiotics in water. Background technique

[0002] Antibiotics are a class of secondary metabolites produced by microorganisms (including bacteria, fungi, and actinomycetes) or higher animals and plants in the course of life, which have anti-pathogen or other activities, and can interfere with the development and function of other living cells. chemicals. In recent decades, due to the widespread use of antibiotics in medicine, animal husbandry and aquaculture, etc., excessive and incomplete metabolism make antibiotics often detected in natural water, sewag...
