Bone meal modified activated carbon and preparation method thereof

Abstract

The invention relates to bone meal modified activated carbon which is prepared from the following raw materials in parts by weight: 80-90 parts of activated carbon, 40-50 parts of bone meal, 4-6 parts of aluminum sulfate, 8-10 parts of sodium metasilicate, 8-10 parts of paligorskite, 3-5 parts of copper sulfate, 7-9 parts of kieselguhr, 2-3 parts of chloramine-T, 4-6 parts of polyethylene glycol, 4-5 parts of modified kieselguhr and a right amount of water. According to the invention, the bone meal is subjected to high-temperature carbonization to form a shape having a developed pore structure and a large specific surface area, and the adsorption rate for heavy metal (such as Cu, Pb, Hg, Cr, Cd and the like) ions is 70-98%; the paligorskite and kieselguhr are further used, so that the effects of bacterium resistance, deodorization, moisture absorption, catalysis and binding property can be achieved, thus ensuring that the activated carbon is less prone to disintegrate; by adding the aluminum sulfate, water pollutants can be flocculated; and by adding the chloramine-T at the same time, sterilization and disinfection can be realized. The activated carbon provided by the invention is suitable for daily air purification and water purification, and has favorable application prospects.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a bone powder modified activated carbon and a preparation method thereof. Background technique [0002] Environmental pollution has been widely valued by people. At present, the pollutants in the air are mainly gases 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. [0003] At present, adsorbents are often used to remove toxins, mainly silica gel, activated alumina, activated carbon, molecular sieves, etc., and there are also adsorption materials developed for the selective adsorption of certain components. However, most of these adsorbents have limited adsorption capacity, and different...
