CN104084132A - Ammonia gas adsorption cleaning agent and preparation method thereof - Google Patents

Abstract

The invention aims at providing an ammonia gas adsorption cleaning agent and a preparation method thereof. According to the technical scheme for achieving the aim, the preparation method comprises the following steps: grinding coal-fired slag; fetching a certain amount of slag powder and flushing with water for several times to remove soluble impurities; drying at 104 DEG C for 4h; adding 20ml of citric acid solutions with different concentration; shaking at 20-50 DEG C for 2h and standing for 12h-32h; filtering out impregnation liquid; heating at 90-110 DEG C in a drying oven for 2h, and washing till the solution is neutral; drying at 105 DEG C for later use to obtain the adsorption cleaning agent.

Description

A kind of purificant for adsorbing ammonia gas and preparation method thereof

Technical field

The present invention relates to ammonia adsorbing domain, be specifically related to a kind of purificant for adsorbing ammonia gas 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.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 purificant for adsorbing ammonia gas 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:

By broken coal furnace ground-slag, get a certain amount of pulverized slag, water rinses for several times, remove soluble impurity, dry 4h at 104 DEG C, then adds the citric acid solution of 20ml variable concentrations, is at 20-50 DEG C, to vibrate after 2h to leave standstill 12-32h in temperature, elimination maceration extract, at drying box 90-110 DEG C of heating 2h, be then washed till neutrality, dry at 105 DEG C, for subsequent use, obtain this absorption purifier.

The present invention has following distinguishing feature:

(1) invent described absorption purifier, raw material sources are extensive, cheap;

(2) invent described absorption purifier preparation method simple, adsorption rate is high;

(3) invent described absorption purifier stable performance, the life-span is long, can preserve for a long time use.

detailed description of the invention:

Embodiment 1:

By broken coal furnace ground-slag, take 100 g flyash, water rinses for several times, remove soluble impurity, dry 4h at 104 DEG C, then adds the citric acid solution of 20% concentration of 20ml, is at 20 DEG C, to vibrate after 2h to leave standstill 12h in temperature, elimination maceration extract, at 90 DEG C of heating 2h of drying box, be then washed till neutrality, dry at 105 DEG C, for subsequent use, obtain this absorption purifier.

Embodiment 2:

By broken coal furnace ground-slag, take 100 g flyash, water rinses for several times, remove soluble impurity, dry 4h at 104 DEG C, then adds the citric acid solution of 20% concentration of 20ml, is at 30 DEG C, to vibrate after 2h to leave standstill 24h in temperature, elimination maceration extract, at 100 DEG C of heating 2h of drying box, be then washed till neutrality, dry at 105 DEG C, for subsequent use, obtain this absorption purifier.

Embodiment 3:

By broken coal furnace ground-slag, take 100 g flyash, water rinses for several times, remove soluble impurity, dry 4h at 104 DEG C, then adds the citric acid solution of 40% concentration of 20ml, is at 40 DEG C, to vibrate after 2h to leave standstill 32h in temperature, elimination maceration extract, at 110 DEG C of heating 2h of drying box, be then washed till neutrality, dry at 105 DEG C, for subsequent use, obtain this absorption purifier.
