Description
Technical field
Preparation and its application method the present invention relates to a kind of room temperature ammonia efficient process material, especially with compound gold
The ammonia decontamination material with high anti humility performance is made in the method for belonging to salt and acid solution step-by-step processing, belongs 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 at normal atmospheric pressure
DEG C, be under room temperature colourless irritant stench smell, it is soluble easily in water.Promulgated in country in 2002《Indoor air quality
Standard》Strict regulations, wherein air have been done to PM10, bacteria containing amount, ammonia amount etc. in room air in (GB/T 1883-2002)
Middle ammonia sanitary standard (maximum permissible concentration) is 0.20 mg/m3.The influence of ammonia is mostly derived from its high alkalinity and height is water-soluble
Property, the respiratory system and skin of human body can mainly be damaged.
In general, when ammonia concentration reaches 5 ppm, will be arrived by human body sensory;When ammonia concentration reaches 20 ppm
During the above, it will cause serious injury to multiple systems such as the respiratory tract of human body, alimentary canals.Sucking in a short time after a large amount of ammonias can
Appearance is shed tears, pharyngalgia, hoarseness, cough, phlegm can with the trace of blood, uncomfortable in chest, expiratory dyspnea, can with headache, dizzy, nausea, vomit
Tuhe is weak to wait ill symptoms, and severe patient can occur pulmonary edema, adult respiratory distress syndrome, edema of the larynx spasm or bronchus and glue
Film necrosis comes off lethal.
At present, indoor air purifying process mainly have photochemical catalytic oxidation, activated carbon adsorption, biocatalyst, ozone oxidation,
The multiple technologies means such as precious metal catalyst oxidation, high efficiency particulate air and negative oxygen ion.Wherein, photocatalysis needs substantial amounts of ultraviolet
Light, and it is very small to the effect of ammonia;Simple activated carbon adsorption anti humility performance is poor, and easily saturation causes secondary pollution;It is raw
The thing catalyst reaction time is longer, and pollutant fast and effectively can not be removed;Ozone oxidation is primarily directed to some and waves
Hair property organic gas, it is impossible to effectively handle ammonia;Precious metal catalyst oxidation industrialization causes industrial prospect because its cost is excessive
It is uncertain;High efficiency particulate air and negative oxygen ion are more directed to some solid contaminants.Therefore, research and develop one kind can have compared with
Big adsorption capacity, the novel strong ammonia gas absorption material of humidity-proof ability at the same time of absorption mode is also the numerous researchers of air purification field
Goal in research.
Based on above target, the researcher of various countries has also done substantial amounts of research work, passes through one to occurring in field
A little new materials carry out acidifications or are formed organic framework structured to achieve certain effect(1、 Doonan, C. J.;
Tranchemontagne, D. J.; Glover, T. G.; Hunt, J.R.; Yaghi, O. M. Exceptional

Oxide and Graphite Oxide/MnO2 Composites as Reactive Adsorbents of Ammonia
atAmbient Conditions. Micro. Meso. Mater. 2012, 150, 55−63.).But in the studies above,
Used method is all more complicated, and raw material also costly, are unfavorable for industrialized production, and is to be directed to single performance mostly
Studied, do not take into account many factors such as adsorption capacity, absorption property and use environment at the same time.Meanwhile for current
The increasing market demand, the country also have many researchers to research and develop ammonia gas absorption material, such as CN
101279236A reports a kind of purificant for adsorbing ammonia gas and preparation method thereof, handles to have obtained phase by simple acid solution
The material answered, but temperature is relatively low in its preparation process, and ageing time is shorter, effectively can not form acidity in porous material surface
Group, and anti humility performance, easy saturation are not considered.And CN 101264434A and CN 103111255A etc. is then reported using boiling
Mountain flour, kaolin, Blumea oil etc. are a kind of ammonia gas absorption agent preparation method of raw material, and absorption ammonia is efficient, but can equally deposit
Adsorption capacity is too small, anti humility performance is poor the shortcomings of.
Therefore, prepare a kind of can have high anti humility performance and the ammonia gas absorption of adsorption capacity at the same time in efficient absorption ammonia
Agent tool is of great significance.
The content of the invention
Preparation and its application method the invention discloses a kind of room temperature ammonia efficient process material, belong to indoor air purification
Treatment process field.It is an object of the invention to provide a kind of ammonia gas absorption material, and the material anti humility performance is good, has more micropores
Structure, specific surface area is big, and a large amount of acidic-groups are contained on surface, and adsorption capacity is big, and adsorption rate is fast, and anti humility performance is good, can be quick
Ammonia in long-acting adsorption cleaning air, can meet under indoor true environment for a long time(>3000 h)Adsorption cleaning ammonia is wanted
Ask.
