Embodiment Construction

[0010] A silica-modified activated carbon, made of the following raw materials in parts by weight (kg): activated carbon 96, silica 22, alum 6, zeolite powder 8, nano-kaolin 5, CuSO4 5, Fe(NO3) 2 7, Artemisia argyi oil 4, modified diatomaceous earth 5, appropriate amount of water;

[0011] The modified diatomite is made of the following raw materials in parts by weight (kg): 145 diatomite, 11 alum, 1.5 nano-carbon, 1.5 barley oil, 2.5 ascorbic acid, 1.6 citric acid, 2.4 sodium tripolyphosphate, ginseng powder 2.4; the preparation method is to put the diatomite in a calciner and calcinate at 550°C for 3.6 hours, take it out, soak it in 13% hydrochloric acid solution for 4.5 hours, filter it out, wash it repeatedly with clean water, dry it, add it to water, At the same time, add nano-carbon, ascorbic acid, citric acid and alum, grind to obtain a slurry, spray dry, mix other remaining ingredients with dry powder, grind and disperse evenly.

[0012] The preparation method of the ...

Abstract

The invention relates to a silicon dioxide modified activated carbon which is prepared from the following raw materials in parts by weight: 90-100 parts of activated carbon, 20-25 parts of silicon dioxide, 5-7 parts of alum, 7-9 parts of zeolite powder, 4-6 parts of nano kaolin, 4-6 parts of CuSO4, 6-8 parts of Fe(NO3)2, 3-5 parts of Blumea oil, 4-5 parts of modified kieselguhr and right amount of water. By modifying the activated carbon with silicon dioxide, the activated carbon has the advantages of favorable adsorption action, low cost and no toxicity, and can be easily regenerated; the added zeolite powder and nano kaolin can catalyze the decomposition of organic substances, resist bacteria, remove odor, absorb moisture and prevent mold; the Blumea oil can shed perfume, and has a protective action on the patients with asthma; and the alum, CuSO4 and Fe(NO3)2 can implement disinfection and purify water. The activated carbon has the advantages of simple technique, lower cost and favorable development prospects.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a silica-modified activated carbon and a preparation method thereof. Background technique [0002] At present, air pollution has seriously affected people's production and life, so air purification has to be taken seriously. Adsorbents are often used in air purification, mainly activated alumina, activated carbon, and adsorption materials developed for selective adsorption of certain components. However, most of these adsorbents have limited adsorption capacity, and different adsorbents need to be studied according to different requirements to play the best role. At the same time, look for new raw materials to enhance the adsorption effect and save costs. With the continuous improvement of people's requirements for quality of life, it is also necessary to provide adsorbents that are beneficial to the human body. Contents of the invention [0003] The object of th...
