Abstract

The invention discloses a haloamine-type macromolecular compound modified mesoporous material. A preparation method of the mesoporous material comprises the following steps of: (1) dissolving a haloamine-type macromolecular compound in a mixed solvent of water and alcohol, then adding amesoporous material and ultrasonically dispersing to be uniform; (2) adjusting the temperature of the reaction system to 60-80 DEG C, reacting for 8-16 hours, and then drying for 3-6 minutes at a temperature of 140-160 DEG C, and then washing, centrifuging and preparing a crude modified mesoporous material product; (3) placing the obtained crude modified mesoporous material product in a sodium hypochlorite solution, stirring and reacting at a room temperature, washing, centrifuging, drying and thus obtainingthe haloamine-type macromolecular compound modified mesoporous material. The modified mesoporous material disclosed by the invention can be used as a treating agent of phenolic compounds in an aqueous solution, and has double functions of physical absorption and chemical removal.

Description

technical field [0001] The invention relates to the technical field of macromolecular synthesis, in particular to an application of modifying mesoporous materials with halogenated amine macromolecular compounds and using the same to process phenolic compounds. Background technique [0002] Among all known single benzene ring compounds, phenolic compounds occupy a large proportion. Such compounds widely exist in industrial waste water and waste gas such as steel mills, paper mills, and petrochemical enterprises. Due to their high solubility and stability in water, phenolic compounds are difficult to be absorbed by soil and naturally degraded by the environment, making them one of the main compounds of industrial pollution. It is well known that phenolic compounds are highly toxic to microorganisms, animals, plants, and humans, and have the potential to induce cancer. Therefore, the United States Environmental Protection Agency (USEPA), the International Organization for Env...
