Description

SRR free radical cluster medicament for treating compound pollution of relatively closed space at one time
Technical Field
The invention belongs to the field of chemistry, and particularly relates to an SRR free radical cluster medicament for treating compound pollution, and a preparation method, application and application thereof.
Background
The world health organization summarizes the health-affecting factors as follows: health is 60% lifestyle + 15% genetic factors + 17% environmental factors + 8% medical factors. Therefore, the environment is an important factor affecting human health. Especially indoor pollution in relatively closed environment, and has the characteristics of more pollutants, easy accumulation, miscellaneous pollution sources, lasting pollution and uneasy detection. Including physical contamination, chemical contamination, and biological contamination. Through years of research by relevant experts and scholars, in a relatively closed space, biological and chemical risk factors related to health mainly include:
(1) the kitchen oil fume is elegant and is the most important pollution source for families. More than 200 harmful substances including acrolein, 3, 4-benzopyrene, dinitrophenol DNP, butadiene, phenol, aliphatic oxide, polycyclic aromatic hydrocarbon, volatile nitrosamine, ketone, lactone, heterocyclic amine compound and the like are detected, and 74 chemical substances which can change cells, cause male sterility, induce tumor, damage cell chromosomes and the like are included.
(2) Indoor articles and decoration are main pollution sources of families. Comprises more than 200 toxic and harmful substances such as formaldehyde, benzene, toluene, xylene, TVOC, ammonia, butyl acetate, trichloroethylene, trichloromethane, undecane and the like, wherein more than 20 carcinogenic substances exist.
(3) The bad smell in the toilet and the sewer is the main pollution area of the family. Human excrement and organic substances in washing water, hydrogen sulfide, mercaptan, dimethyl mercaptan, hexyl amine, indole, nitrogen hydride and garlic odor, leek odor, irritant odor, putrefactive fish odor and the like generated by the action of microorganisms, pathogenic bacteria, pathogenic protozoa, mold, cockroaches and the like.
(4) The living pollution is an important pollution source for families. The method comprises the following steps of removing a large number of pollutants from respiratory tracts and skin sweat glands of family members, emitting various pathogenic bacteria and various smells of gas by respiration, and infecting various pathogenic microorganisms such as: influenza virus, mycobacterium tuberculosis, streptococci, etc. enter the indoor environment through sneezing and coughing.
(5) Indoor TVOCs (researchers of indoor air quality often refer to all indoor organic gaseous substances they sample for analysis as TVOCs) are important pollutants of indoor air. Containing hydrocarbons, halogenated hydrocarbons, oxygenated hydrocarbons and nitrogen hydrocarbons, which comprises: benzene series, organic chloride, freon series, organic ketone, amine, alcohol, ether, ester, acid and petroleum hydrocarbon compound. At present, 350 kinds of volatile organic compounds have been identified indoors, particularly aromatic hydrocarbons (such as formaldehyde), aliphatic hydrocarbons (such as n-nonane to n-undecane), formaldehyde, benzene and benzene series, chloroform and aromatic hydrocarbons. The main sources are decoration adhesive, cleaning agent, deodorant and insecticide.
(6) Indoor mould, virus and pathogenic bacteria. Including bacteria, fungi, filterable viruses, and biological organic components. The indoor air biological pollution factors mainly include the following factors: mould, dust mite, legionella, animal dander, bioactive substances and inhalable particles. A canadian survey showed that 21% of indoor air quality problems were caused by microbial contamination.
It is known that the above six indoor risk factors are important causes of chronic diseases such as cardiovascular and cerebrovascular diseases, diabetes, cancer, chronic respiratory diseases, etc. Therefore, the control of the dangerous factors and the implementation of comprehensive pollutant treatment can continuously improve the air quality of living environment, reduce the influence of environmental pollution on health, and create health supporting environment, which becomes necessary for everyone, every family and society! Currently, the disinfectant for controlling biological pollution in the market is mainly a chlorine-containing preparation; the air purifying agent for controlling chemical pollution is mainly used for shielding the fragrant agent. The product has the advantages of various varieties, difficult scientific use, poor effect, great secondary pollution or injury, and no product for solving various composite pollution at one time.
The advanced free radical active oxygen oxidation technology is to utilize free radicals to degrade or mineralize VOCs pollutants and oxidize and kill pathogenic bacteria, and is the leading-edge technology in the disinfection and air purification field in the world at present and the key point of domestic and foreign research. The existing advanced oxidation technology mainly comprises O3(ozone) Oxidation, SO4 -The degradation steps of (sulfate radical), OH (hydroxyl radical) and the like are divided into direct degradation and indirect degradation. Wherein the indirect degradation is via O3Oxidizing agent and H2O action generationOH, or with O2Reaction to form O3Thereby degrading or mineralizing the organic pollutants. OH and O have the defects of low quantum yield, short survival time, selectivity to mineralization of organic pollutants, secondary pollution of ozone and the like. Advanced oxidation technology based on hydroxyl free radicals and sulfate free radicals is the key point of research at home and abroad in recent years in pollutant end treatment, but only the hydroxyl free radicals or the sulfate free radicals are independently adopted. Because the VOCs with different chemical structures have different stress selectivity, the degradation rates of the VOCs by free radicals generated by different activation modes and conditions are different, and the mineralization effects of different types of free radicals are different due to different contents of the VOCs. Therefore, in practical application, the method of singly adopting hydroxyl radicals or sulfate radicals has the defects of low oxidation efficiency, toxic byproducts of oxidation products, incomplete disinfection and sterilization and the like.

The inorganic free radical source is at least one of potassium monopersulfate, potassium persulfate or sodium persulfate. The inorganic free radical source functions to provide an initial free radical component, the radical Sulfate (SO)4 —·.) to initiate a subsequent series of free radical reactions.
The composite irritation agent is composed of 0.5-5 parts of sodium perborate, 1-20 parts of sodium carbonate, 0.05-2 parts of alpha-hydroxyalkyl benzophenone and 0.5-5 parts of sodium lignosulphonate. The composite excitant has the function of pertinently controlling the types and quantum yield of the free radical clusters so as to adapt to the mineralization and decomposition of VOC malodorous substances with different structures and different concentrations. When the content of the composite irritant is too high, the free radical clusters are generated too fast and can collide with each other to be lost in a system, and when the content of the composite irritant is too low, the quantum yield of the free radicals is not high, and the overall activity is insufficient.
