Abstract

The invention provides a grain husk modified activated carbon adsorbent prepared from the following raw materials in parts by weight: 100-120 parts of activated carbon, 40-45 parts of camellia oleifera husks, 30-34 parts of peanut husks, 20-23 parts of sunflower seed husks, 4-5 parts of castor oil plant husks, 12-14 parts of diatomite, 8-10 parts of modified attapulgite and a proper amount of water. Grain such as camellia oleifera husks and the like is carbonized to obtain activated carbon which has different pore diameters and can absorb harmful substances with different molecular dimensions; meanwhile, the novel applications of various grain husks are also developed, the cost is reduced, and the grain husk modified activated carbon adsorbent is environment-friendly and efficient. The modified attapulgite is also added to effectively desulfurize, and jade powder and medical stone powder which are beneficial to the health of a human body are also added, so that the grain husk modified activated carbon adsorbent is healthy and environment-friendly.

Description

technical field [0001] The invention relates to a method for modifying non-metallic minerals, in particular to a grain husk modified activated carbon 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 c...
