Adsorbing material for efficiently removing nitrogen-containing organic matters in water body and preparation method of adsorbing material

The invention relates to an adsorption material for efficiently removing nitrogen-containing organic matters such as tetracycline antibiotics in a water body and a preparation method of the adsorption material. The method is characterized in that a porous material with a large specific surface area is used as a matrix, and inorganic metal ions and organic groups are modified on the inner surfaces and the outer surfaces of pores of the matrix. The invention discloses an adsorption material for efficiently removing nitrogen-containing organic matters such as tetracycline antibiotics in a water body and a preparation method of the adsorption material. The adsorption material has the characteristics of large adsorption capacity, high adsorption rate and the like. Experiments prove that the adsorption material is simple in preparation process, large in adsorption capacity, ultra-fast in adsorption rate and renewable, especially has a selective adsorption effect on nitrogen-containing organic matters such as tetrac
