Description

technical field [0001] The invention belongs to the technical field of antivirus sprays, in particular to a photocatalytic apatite encapsulation technology special antivirus spray. Background technique [0002] According to the World Health Organization (WHO) statistics, 80% of the diseases in developing countries are caused by pathogenic microorganisms, including parasites, protozoa, fungi, bacteria, B krilletts, viruses and nasty viruses ⑴. These microorganisms can cause serious diseases in the human body, such as diarrhea, tuberculosis, pneumonia, typhoid fever, etc. [0003] At present, traditional disinfection methods mainly include chlorine gas, ozone and ultraviolet light. Among them, chlorine disinfection is recognized as the most effective, but this process will generate teratogenic and carcinogenic disinfection by-products, including trihalomethanes, haloacetic acids, etc., resulting in secondary pollution and water salinization. Ozone disinfection also generate...
