Embodiment 1

[0018] A preparation method for ammonia removal material, specifically as follows: Weigh 500g NaY molecular sieve, add 140g phosphoric acid and mix uniformly, then add 10g glycerin, after fully mixing uniformly, add 50g tartaric acid, mix uniformly, add deionized water and knead, extrude Into strips, drying, that is ammonia removal material. The obtained ammonia removal material was tested according to ASTM D6646-01 method, and the ammonia adsorption capacity was 0.017g / cc.

Embodiment 2

[0020] A preparation method for ammonia removal material, specifically as follows: Weigh 500g of NaY molecular sieve, add 350g of copper sulfate pentahydrate and mix evenly, then add 50g of squid powder, mix well, add 150g of citric acid, mix evenly, add deionized water Kneading, extruding and drying to obtain the ammonia removal material. The obtained ammonia removal material was tested according to ASTM D6646-01 method, and the ammonia adsorption capacity was 0.040 g / cc.

Embodiment 3

[0022] A method for preparing an ammonia removal material, specifically as follows: Weigh 500g of NaY molecular sieve, add 150g of phosphoric acid and 100g of copper sulfate pentahydrate, mix well, then add 75g of glycerin, mix well, add 350g of kaolin, mix well, add deionized Kneading with water, extruding and drying to obtain the ammonia removal material. The obtained ammonia removal material was tested according to ASTM D6646-01 method, and the ammonia adsorption capacity was 0.031g / cc.

Abstract

The invention discloses a preparation method of an ammonia removal material. The preparation method comprises the steps of: uniformly mixing NaY molecular sieves, ammonia removal effective constituents and a lubricating agent, then adding a binder and deionized water for kneading, carrying out extrusion forming, and drying to obtain the ammonia removal material, wherein the weight ratio of the NaY molecular sieves, the ammonia removal effective constituents and the lubricating agent is 1:0.2-0.7:0.02-0.15:0.1-0.7. The ammonia removal material has the advantages of being mild in a preparation technology, efficient and economic, having high repeatability and high strength, resisting high temperature and being suitable for removal of ammonia gas in industrial exhaust gas, sewage treatment plants and interior of rooms. The ammonia removal material provided by the invention is safe, non-toxic and low in cost. The invention provides an effective solution for ammonia pollution problem.

Description

technical field [0001] The invention relates to a preparation method of an ammonia removal material. Background technique [0002] Ammonia is a colorless gas with a strong pungent odor, lighter than air (specific gravity 0.5869), and is a 2 and NO 2 One of the most abundant nitrogen-containing compounds in the world. The volatilization of ammonia gas into the atmosphere will cause acid rain, and with the rainfall, it will be deposited in water or soil, causing eutrophication of plants or changing the ecological structure, thereby affecting biological diversity. The lowest ammonia concentration that can be sensed by the human body is 5.3ppm. When the concentration is high, there will be a strong irritating odor, which will corrode and stimulate the skin tissue it contacts, and will also cause great damage to human tissue. Short-term inhalation of large amounts Symptoms such as tearing, sore throat, chest tightness, headache, nausea, and dyspnea will appear after ammonia ga...
