Embodiment Construction

[0011] A kind of chestnut shell activated carbon is made from the following raw materials in parts by weight (kg): chestnut shell 130, zinc chloride 4, gum arabic 5, polyvinylpyrrolidone 5, bentonite 27, aluminum oxide 13, pumice 23, lanthanum chloride 3. Cerium chloride 3, scandium chloride 3, yttrium chloride 3, praseodymium chloride 3, lanthanum nitrate 3, cerium nitrate 2, scandium nitrate 1, yttrium nitrate 1, praseodymium nitrate 1, modified diatomite 4, water Appropriate amount;

[0012] The 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, Dried, added to...

Abstract

Chestnut shell active carbon is prepared by the following raw materials by weight: 120-140 parts of chestnut shell, 3-5 parts of zinc chloride, 4-6 parts of Arabic gum, 4-6 parts of periston, 25-30 parts of bentonite, 10-15 parts of alumina, 20-25 parts of pumice, 2-4 parts of lanthanum chloride, 2-4 parts of cerium chloride, 2-4 parts of scandium chloride, 2-4 parts of yttrium chloride, 2-4 parts of praseodymium chloride, 1-3 parts of lanthanum nitrate, 1-3 parts of cerium nitrate, 1-2 parts of scandium nitrate, 1-2 parts of yttrium nitrate, 1-2 parts of praseodymium nitrate, 4-5 parts of modified diatomite, and a proper amount of water. Chestnut shell is used as a raw material, so as that the active carbon has advantages of developed aperture structure, big specific surface area, high adsorption speed, and good adsorption capability on various solutes and dissociation gases; lanthanum chloride is used for activation so as to form active carbon, which has big gaps and strong adsorption capability, is suitable for absorbing organic matters in air and water and removing harmful substances like formaldehyde, is low in cost, and is suitable for industrialization production.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a chestnut shell 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, and ...
