Embodiment Construction

[0011] A highly adsorptive modified activated carbon is characterized in that it is made of the following raw materials in parts by weight (kg): grapevine 35, sawdust 45, activated carbon 110, corn cob 35, potassium hydroxide 8, sodium lauryl sulfate or Polyethylene glycol 8, urea 8, zinc nitrate 4, nickel nitrate 4, gum arabic or sodium alginate 12, modified diatomite 4, appropriate amount of water;

[0012] Modified diatomite is made from the following raw materials in parts by weight (kg): diatomite 105, jade 22, nano-carbon 1.5, sodium benzoate 1.4, angelica oil 1.5, silane coupling agent KH550 1.6, sodium selenite 1.5, Lily powder 2.5; the preparation method is to put diatomaceous earth and jade into a calciner and calcinate at 560°C for 3.6 hours, take it out, soak it in 13% hydrochloric acid solution for 4 hours, filter it out, wash it repeatedly with clean water, and dry it , into water, and at the same time, add nano-carbon, sodium selenite, sodium benzoate, and lily ...

Abstract

The invention relates to high-adsorptivity modified activated carbon which is prepared from the following raw materials in parts by weight: 30-40 parts of grape vine, 40-50 parts of sawdust, 100-120 parts of activated carbon, 30-40 parts of corn cob, 6-9 parts of potassium hydroxide, 7-10 parts of sodium lauryl sulfate or polyethylene glycol, 7-10 parts of urea, 2-5 parts of zinc nitrate, 2-5 parts of nickel nitrate, 10-14 parts of Arabic gum or sodium alginate, 7-10 parts of modified attapulgite and a right amount of water. According to the invention, the grape vine, sawdust and corn cob are subjected to high-temperature heat treatment, and the prepared activated carbon has large specific surface area, realizes new application of wastes and achieves the effects of convenient carbonization activation process and less pollutant discharge; and by using the potassium hydroxide, urea, zinc nitrate and nickel nitrate substances for modification, the activated carbon increases the gap and enhances the adsorption capacity. Besides, the high-adsorptivity modified activated carbon is accessible in raw materials, simple in process, low in cost and suitable for industrial production, causes no generation of harmful substances and has favorable application prospects.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a high-adsorption modified activated carbon 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 conditio...
