Embodiment Construction

[0011] A modified straw charcoal adsorbent, made of the following raw materials in parts by weight (kg): straw charcoal 117, zeolite powder 9, medical stone powder 8, acrylamide 8, diatomite 8, citric acid 18, EDTA3, Sodium tripolyphosphate 5, modified diatomite 4, appropriate amount of water;

[0012] The modified diatomite is made of the following raw materials in parts by weight (kg): diatomite 125, sepiolite 11, nano-carbon 1.5, clove oil 2.5 ascorbic acid 1.5, sodium alginate 2.6, kaolin 33, gynostemma powder 3.5 The preparation method is to put diatomite and sepiolite into a calciner and calcinate at 550°C for 3.5 hours, take it out, soak it in 14% hydrochloric acid solution for 4 hours, filter it out, wash it repeatedly with clear water, and dry it. Add water, at the same time, add nano-carbon, ascorbic acid, kaolin, grind to obtain slurry, spray dry, mix other remaining ingredients with dry powder, grind and disperse evenly.

[0013] The preparation method of the plat...

Abstract

The invention relates to a modified straw wood charcoal adsorbent which is prepared from the following raw materials in parts by weight: 110-120 parts of straw wood charcoal, 8-10 parts of zeolite powder, 7-9 parts of medical stone powder, 7-9 parts of acrylamide, 6-9 parts of kieselguhr, 16-20 parts of citric acid, 3-4 parts of EDTA (ethylene diamine tetraacetic acid), 4-6 parts of sodium tripolyphosphate, 4-5 parts of modified kieselguhr and right amount of water. The zeolite, medical stone, kieselguhr and other rock powders used for modification can enhance the adsorptivity, implement microbial resistance, deodorization, moisture absorption, mold prevention and desulfurization, and catalyze the decomposition of organic substances; the acrylamide can flocculate pollutants in water; by using the straw wood charcoal as the substrate, the adsorbent has the advantages of developed pores, high adsorption capacity and low cost, and is suitable for industrial production; and the adsorbent is suitable for daily air and water purification, and also suitable for treating industrial wastewater and waste gas.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a modified straw charcoal adsorbent and a preparation method thereof. Background technique [0002] With the development of science and technology and the gradual construction of modern industries, various chemicals have been developed and utilized, which has brought convenience to people's lives. The problem. [0003] At present, the pollutants in the air are mainly the gas produced by industrial fuel combustion, automobile exhaust, and toxic and harmful gases produced in production. Water pollution is mainly due to the fact that the sewage discharged from industrial production contains a large amount of toxic substances, and the sewage produced in people's daily life produces many harmful substances. There are many times in people’s lives that people need to remove toxins. For example, there are many bacteria and toxins on the filter screen of air conditioners, an...
