Description
Technical field
The present invention relates to preparation and using method thereof that a kind of normal temperature ammonia efficiently processes material, particularly adopt the method for composite metal salt and acid solution step-by-step processing to obtain the ammonia decontamination material with high anti humility performance, belong to indoor air purification Treatment process field.
Background technology
Ammonia relative molecular mass is 17.03, and fusing point is-77.74 DEG C, and boiling point is-33.43 DEG C at normal atmospheric pressure, is the smell of colourless irritant stench under normal temperature, soluble in water.Country in 2002 promulgate " Indoor Air Quality standards " (GB/T1883-2002) in room air in PM10, bacteria containing amount, ammonia amount etc. done strict regulations, wherein Ammonia in Air gas sanitary standard (maximum permissible concentration) is 0.20mg/m
3.The impact of ammonia mainly comes from its high alkalinity and highly-water-soluble, mainly can damage the respiratory system of human body and skin.
In general, when ammonia concentration reaches 5ppm, will be arrived by human body sensory; When ammonia concentration reaches more than 20ppm, will cause serious injury to multiple systems such as the respiratory tract of human body, alimentary canals.Can occur after sucking a large amount of ammonia in a short time shedding tears, pharyngalgia, hoarseness, cough, phlegm can be with the trace of blood, uncomfortable in chest, expiratory dyspnea, can with headache, dizzy, Nausea and vomiting and the ill symptoms such as weak, pulmonary edema, ARDS, edema of the larynx spasm or tunica mucosa bronchiorum necrosis can be there is and come off lethal in severe patient.
At present, indoor air purifying process mainly contains the multiple technologies means such as photochemical catalytic oxidation, charcoal absorption, biocatalyst, ozone oxidation, precious metal catalyst oxidation, high efficiency particulate air and negative oxygen ion.Wherein, photocatalysis needs a large amount of ultraviolet lights, and very little to the effect of ammonia; Simple charcoal absorption anti humility performance is poor, and very easily saturatedly causes secondary pollution; The biocatalyst reaction time is longer, cannot remove fast and effectively pollutant; Ozone oxidation mainly for be some VOCs, effectively can not process ammonia; Precious metal catalyst oxidation industrialization, because of its high cost, causes industrial prospect uncertain; High efficiency particulate air and negative oxygen ion more spininess right be some solid contaminant.Therefore, research and development one can have larger adsorption capacity, and the novel simultaneously ammonia gas absorption material that humidity-proof ability is strong of absorption mode is also the goal in research of the numerous researcher of air purification field.
Based on above target, the researcher of various countries has also done a large amount of research work, by some new materials occurred in field are carried out to acidification or formed organic framework structured achieve certain effect (1, Doonan, C.J.; Tranchemontagne, D.J.; Glover, T.G.; Hunt, J.R.; Yaghi, O.M.ExceptionalAmmoniaUptakebyaCovalentOrganicFramework.
