Abstract

The invention relates to a nitrogen hybridized magnetic ordered meso-porous carbon adsorbent. The aperture of the adsorbent is within 3.8nm, the surface part of the adsorbent is graphitized, and the adsorbent comprises magnetic nano particles; the magnetic nano particles are iron oxide nano particles and iron nano particles. A preparation method of the adsorbent comprises the following steps: adding a meso-porous silicon SBA-15 template into an organic solution which contains furfuryl alcohol and ferric nitrate and is easy to volatilize, sufficiently mixing, performing thermal polymerization, subsequently carbonizing on the presence of an inert gas, finally removing silicon by using a strong alkali solution, and separating, washing and drying so as to obtain magnetic ordered meso-porous carbon; and dissolving the magnetic ordered meso-porous carbon into a strong acid solution, controlling the temperature to be less than 5 DEG C, adding aniline and ammonium persulfate, sufficiently mixing, washing and drying the complex after polymerization, and carbonizing on the presence of the inert gas so as to obtain the nitrogen hybridized magnetic ordered meso-porous carbon adsorbent. The adsorbent is high in adsorption efficiency, large in adsorption volume and short in adsorption balance time.

Description

technical field

[0001] The invention relates to an adsorption material, in particular to a nitrogen-hybridized magnetically ordered mesoporous carbon adsorbent, a preparation method and an application. Background technique

[0002] Heavy metals and phenolic organic compounds widely exist in various industrial and agricultural wastewater, which are highly toxic, carcinogenic and water-soluble, and seriously endanger public health and the ecological environment. Heavy metals and phenolic organic substances can invade the human body through diet, skin contact, and even airborne (phenolic organic substances), affecting human health. Therefore, the removal of heavy metals and phenolic organic pollutants in water has attracted widespread attention at home and abroad.

[0003] Chinese patent application No. 201310272004.0 discloses a magnetically loaded iron-loaded ordered mesoporous carbon. The ordered mesoporous carbon is used as a carrier. The carrier is prepared by a hard temp...
