preparation example Construction

[0050] The embodiment of the present invention discloses a method for preparing a magnetic multi-level porous chestnut shell carbon ball-based surface imprinted material, the steps are as follows:

[0051] (1) Preparation of chestnut shell active raw material

[0052] The chestnut shells taken from the chestnut garden of Lushan County, Pingdingshan City, Henan Province were washed with tap water, dried, crushed by a pulverizer, and sieved to 200-300um to make chestnut shell powder; Chestnut shell powder is added to the solution concentration of 10-20% potassium hydroxide solution and stirred, the mass ratio of chestnut shell powder to potassium hydroxide is 1:3-4, heated in a water bath at 60-70°C for 1-3h; 100-120 Vacuum drying at ℃ for 12-24 hours, and grinding to obtain chestnut shell active material.

[0053] (2) Preparation of magnetic hierarchical porous chestnut shell carbon spheres

[0054] Put the ferric nitrate and chestnut shell active raw material mixture with a ...

Abstract

The invention discloses a preparation method of a magnetic hierarchically porous chestnut shell carbon sphere based surface imprinting material. The preparation method comprises following steps: chestnut shell active raw material preparation, magnetic hierarchically porous chestnut shell carbon sphere preparation, and magnetic hierarchically porous chestnut shell carbon sphere based surface imprinting material preparation. The abundant agriculture and forestry waste resources low in cost are taken as raw materials to prepare the magnetic hierarchically porous chestnut shell carbon sphere basedsurface imprinting material which is capable of realizing effective identification, separation, and enrichment of antibiotic residues in the environment from complex systems.

Description

technical field [0001] The invention relates to the technical field of preparation of environmental functional materials, in particular to a magnetic multi-level porous chestnut shell carbon ball-based surface imprinted material and its preparation method and application. Background technique [0002] Cefalexin (CFX) is the first generation of cephalosporin antibiotics, belonging to β-lactam antibiotics, widely used in the treatment of urinary tract infection, respiratory tract infection, skin and soft tissue infection and other diseases. In the process of biological metabolism, most antibiotics are directly excreted in the form of drugs with feces and urine, and finally enter the water environment, becoming potential new pollutants in the environment. Although the antibiotics residues in the environment and food samples may only be at trace levels, they are potentially harmful to humans and aquatic and terrestrial organisms due to their strong persistence, biological reacti...
