Abstract
The invention aims at providing an ammonia compound adsorbent and a preparation method thereof. According to the technical scheme for achieving the purpose, the preparation method of the ammonia compound adsorbent comprises the following steps: crushing fire coal furnace slag, washing a certain amount of furnace slag powder with water for a plurality of times, removing soluble impurities, drying at 104 DEG C for 4 hours, subsequently uniformly mixing solid substances with chitosan according to a certain ratio, adding a certain amount of 1-5mol/L sodium hydroxide solution, oscillating the solution for a certain time, subsequently washing the solution with the water until the solution is neutral, and drying at 104 DEG C for 1-4 hours to obtain the compound absorbent.
Description
Technical field
The present invention relates to ammonia adsorbing domain, be specifically related to a kind of ammonia compound adsorbent and preparation method thereof.
Background technology
Ammonia, inorganic compound, is gas under normal temperature, the gas of colourless irritant stench, soluble in water, when ammonia is water-soluble, amino molecule becomes a hydration ammonia with hydrone by Hydrogenbond, one hydration ammonia energy fraction is ionized into ammonium ion and hydroxide ion, therefore ammoniacal liquor shows alkalescent, the mucous membrane of energy skin ambustion, eyes, respiratory apparatus, people sucks too much, can cause lung swelling, thus dead.
Due to a large amount of generations of municipal sewage and industrial wastewater, and exhaust emissions, cause environment more and more to worsen.Situation day by day serious, causes control imperative.
Absorption method is to process a kind of important physical chemistry method of harmful in waste water and waste gas and difficult degradation pollutant, and active carbon is the most frequently used sorbing material, but due to lack of material, cost is higher, regeneration is difficult etc., and reason is restricted its application.Take industry and agricultural wastes is raw material, and preparation and exploitation are cheap, to replace active carbon be the important directions that sorbing material is studied to efficient adsorption material.
Summary of the invention
The object of this invention is to provide a kind of ammonia compound adsorbent and preparation method thereof, the lack of material existing to overcome prior art, the shortcoming that cost is high.For achieving the above object, the technical solution used in the present invention is as follows:
Coal furnace ground-slag is broken, get a certain amount of pulverized slag, water rinses for several times, remove soluble impurity, at 104 ℃, dry 4h, then mixes solid matter and shitosan according to certain ratio, the sodium hydroxide solution that adds a certain amount of 1-5mol/L, after vibration certain hour, water rinses to neutral, under 104 ℃ of conditions, after dry 1-4h, is this compound adsorbent.
In the present invention, there is following distinguishing feature:
(1) invent described compound adsorbent, raw material sources are extensive, cheap;
(2) invent described compound adsorbent preparation method simple, adsorption rate is high;
(3) invent described compound adsorbent stable performance, the life-span is long, can preserve for a long time use.
the specific embodiment:
Embodiment 1:
Coal furnace ground-slag is broken, take 100 g flyash, water rinses for several times, remove soluble impurity, at 104 ℃, dry 4h, then mixes solid matter and shitosan according to mass ratio 4:1, adding 300ml concentration is the sodium hydroxide solution of 1mol/L, after vibration 1h, water rinses to neutral, under 104 ℃ of conditions, after dry 1h, is this compound adsorbent.
Embodiment 2:
Coal furnace ground-slag is broken, take 100 g flyash, water rinses for several times, remove soluble impurity, at 104 ℃, dry 4h, then mixes solid matter and shitosan according to mass ratio 3:1, adding 300ml concentration is the sodium hydroxide solution of 2mol/L, after vibration 2h, water rinses to neutral, under 104 ℃ of conditions, after dry 1h, is this compound adsorbent.
Embodiment 3:
Coal furnace ground-slag is broken, take 100 g flyash, water rinses for several times, remove soluble impurity, at 104 ℃, dry 4h, then mixes solid matter and shitosan according to mass ratio 2:1, adding 300ml concentration is the sodium hydroxide solution of 5mol/L, after vibration 3h, water rinses to neutral, under 104 ℃ of conditions, after dry 1h, is this compound adsorbent.
Claims (1)
1. the invention discloses a kind of ammonia compound adsorbent and preparation method thereof, for achieving the above object, the technical solution used in the present invention is as follows:
