Wheat straw powder modified active carbon adsorbent and preparation method thereof

Abstract

A wheat straw powder modified active carbon adsorbent is prepared by the following raw materials by weight: 30-40 parts of wheat straw powder, 100-120 parts of active carbon, 8-10 parts of quartz powder, 10-15 parts of bamboo carbon powder, 7-9 parts of lithium carbonate, 7-9 parts of kaolin, 1-2 parts of N,N-dimethyldodecylamine-N-oxide sol, 1-2 parts of coconut diethanolamide, 1-2 parts of silicone resion polyether emulsion, 1-2 parts of polyether modified silicone oil, 4-5 parts of modified diatomite, and a proper amount of water. The wheat straw powder is used as a raw material so as that the prepared active carbon has advantages of low weight, developed aperture structure, big specific surface area, high adsorption speed, and good adsorption capability on various solute and dissociation gases; a methylene blue adsorption value of the prepared active carbon is 1-7 mg / 0.1g; and in the active carbon preparation process, the preparation method has advantages of no acidic waste water and exhaust gas discharge, and low cost, implements waste utilization of crops, reduces environment pollution, is suitable for air purification, and effectively removes harmful substances such as formaldehyde, bacteria and phenol.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a wheat straw powder 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 gases produced by the combustion of industrial fuels, 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 in people's lives produces many harmful substances. There are many times in people's lives that they need to remove toxins. For example, there are many bacteria and toxins on the air conditioner filter, an...
