Abstract
The invention aims at providing an ammonia capture agent with high adsorptivity. According to the technical scheme for achieving the aim, the ammonia capture agent is prepared by the following steps: crushing coal-fired slag, adding a certain amount of slag powder into a hydrochloric acid solution with the mass percentage of 5%, stirring slowly so as to remove surface organisms and other impurities, filtering after 1-5 hours, taking out the product, washing repeatedly by deionized water for several times, then putting into 10%-30% of an oxalic acid solution for digestion, controlling the digestion temperature to be 60-80 DEG C by water bath, taking out after 1-5 hours, putting into a baking oven, baking at 110 DEG C for 30 minutes, and bottling for later use.
Description
Technical field
The present invention relates to ammonia adsorbing domain, be specifically related to a kind of ammonia agent for capturing that has more adsorptivity.
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.Taking industry and agricultural wastes as raw material, 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 agent for capturing that has more adsorptivity, 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:
By broken coal furnace ground-slag, get a certain amount of pulverized slag, put into mass fraction and be 5% hydrochloric acid solution, low rate mixing, to remove surface organic matter and other impurity, filters and takes out after 1-5h, repeatedly rinse several times by deionized water, put into again digestion in the oxalic acid solution of 10-30%, utilize water-bath that digestion temperature is controlled to 60-80 DEG C, after 1-5h, take out and be placed in baking oven 110 DEG C and dry 30min, bottle for subsequent use, obtain this ammonia agent for capturing.
There is following distinguishing feature in the present invention:
(1) invent described ammonia agent for capturing, raw material sources are extensive, cheap;
(2) invent described ammonia agent for capturing preparation method simple, adsorption rate is high;
(3) invent the stable performance of described ammonia agent for capturing, the life-span is long, can preserve for a long time use.
detailed description of the invention:
