Abstract
Boric acid modified active carbon is prepared by the following raw materials by weight: 150-170 parts of wood chip, 15-20 parts of boric acid, 7-9 parts of attapulgite, 5-7 parts of monoglyceride stearate, 7-9 parts of bentonite, 5-7 parts of lime, 4-6 parts of calcium carbonate, 3-5 parts of diethanolamine, 2-4 parts of tetraethylenepentamine, 4-5 parts of modified diatomite, and a proper amount of water. The boric acid modified active carbon is activated and modified by boric acid, so as that the active carbon has uniform texture and developed micropore gaps, and adsorption capability is greatly enhanced; the attapulgite and the bentonite, after high temperature activation, enhance absorption function of the active carbon, and simultaneously have microbe growth inhibition property, acid and alkali resistance, corrosion resistance and mildew resistance; simultaneously, calcium oxide and calcium carbonate are added for high efficiency desulphurization; and wood chip is used as a raw material which has advantages of cost low and environmental protection, and is suitable for gas phase and water phase purification.
Description
technical field [0001] The invention relates to the field of modified functional materials, in particular to a boric acid 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 conditioners,...
