Fluorine removal modified active carbon and preparation method thereof

Abstract

The invention discloses fluorine removal modified active carbon, which is prepared from the following raw materials in parts by weight: 100-110 parts of active carbon, 6-8 parts of medical stone, 10-14 parts of active aluminum oxide, 6-8 parts of alkaline tourmaline, 7-9 parts of diatomite, 1-2 parts of zirconium nitrate, 1-2 parts of strontium nitrate, 2-4 parts of chitosan, 15-20 parts of acetic acid, 4-5 parts of modified diatomite and a right amount of water. According to the method, active aluminum oxide is used for modify the active carbon, so that the active carbon can effectively remove fluorine in water, catalyses decomposition of organics, and is easy to regenerate; natural stones, such as the medical stone and the alkaline tourmaline, are used for modifying the active carbon, so that the active carbon has functions of anti-bacteria and deodorization, moisture absorption, mildew prevention and desulfurization, and can also catalyze decomposition of organics; the chitosan is also used, so that the active carbon can adsorb metal ions, organic mercury, organics and the like, and is safe and non-toxic. The preparation method of the fluorine removal modified active carbon is simple in technology and suitable for industrial production.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a fluorine-removing 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 condit...
