Embodiment 1

[0013] Crush the coal-fired slag, weigh 100 g of fly ash, add 2L of 10% phosphoric acid solution, soak for 3 hours at room temperature, and then dry. After drying, raise the solid substance from room temperature to a preset temperature of 300°C for 2 hours, cool to room temperature, take out the final product and wash it with distilled water until neutral, dry it, and bottle it for later use to obtain the ammonia adsorbent.

Embodiment 2

[0015] Crush the coal-fired slag, weigh 100 g of fly ash, add 2 L of 30% phosphoric acid solution, soak for 12 hours at room temperature, and then dry. After drying, raise the solid material from room temperature to a preset temperature of 500°C for 2 hours, cool to room temperature, take out the final product and wash it with distilled water until neutral, dry it, and bottle it for later use to obtain the ammonia adsorbent.

Embodiment 3

[0017] Crush the coal-fired slag, weigh 100 g of fly ash, add 2 L of 50% phosphoric acid solution, soak at room temperature for 24 hours, and then dry. After drying, raise the solid substance from room temperature to a preset temperature of 700°C for 2 hours, cool to room temperature, take out the final product and wash it with distilled water until neutral, dry it, and bottle it for later use to obtain the ammonia adsorbent.

Abstract

The invention aims to provide an ammonia adsorbent and a preparation method thereof. The technical scheme adopted by the invention is as follows: furnace slag of coal is smashed, a certain amount of furnace slag powder is taken, a phosphoric acid solution with the concentration of 10-50% is added, impregnating is carried out at the room temperature for 3-24h, and then drying is carried out; after drying, solid matters are heated from the room temperature to the preset temperature (300-700 DEG C), the temperature is kept for 2h, then the heated solid matters are cooled to the room temperature, and the final product is taken out, and is washed with distilled water to be neutral, dried, and bottled for standby, so that the ammonia adsorbent can be obtained.

Description

technical field [0001] The invention relates to the field of ammonia gas adsorption, in particular to an ammonia adsorbent and a preparation method thereof. Background technique [0002] Ammonia gas, an inorganic compound, is a gas at room temperature, a colorless gas with an irritating odor, and is easily soluble in water. When ammonia dissolves in water, ammonia molecules and water molecules combine to form monohydrate ammonia through hydrogen bonds, and monohydrate ammonia can form a small part It is ionized into ammonia ions and hydroxide ions, so ammonia water is weakly alkaline, which can burn the skin, eyes, and mucous membranes of respiratory organs. If people inhale too much, it can cause lung swelling and even death. [0003] Due to the massive generation of urban sewage and industrial waste water, as well as exhaust emissions, the environment is getting worse and worse. The situation is becoming more and more serious, which makes the management work imperative. ...
