Abstract

The invention relates to a method for preparing magnetic / hollow double-shell layer print adsorbent by emulsion polymerization and belongs to the technical field of the preparation of environment function materials. Attapulgite is used as stabilizer; a few Fe3O4 nanometer particles are used as a magnetic separation carrier; a dispersion solution of hydrophilic Fe3O4 nanometer particles and attapulgite is used as a water phase; and a mixture of organic solvent hexadecane, cross-linking agent styrene, template molecule cyhalothrin, initiator azo isobutyric dimethyl ester and functional monomers acrylamide and tetra-vinyl pyridine is used as an oil phase. The water phase and the oil phase are mixed to prepare stable oil-in-water emulsion in an ultrasonic manner; and the magnetic hollow double-shell layer print polymer is prepared by emulsion polymerization. The magnetic hollow double-shell layer print polymer can be applied to selective recognition and separation of cyhalothrin in an aqueous solution. The magnetic hollow double-shell layer print polymer has a hollow double-layer structure, wherein the hollow structure can be used for effectively increasing adsorption capacity; the strength of the obtained printer polymer is enabled to be high by the inorganic particle layer in the shell layer; and the recognition points are unlikely to be damaged.

Description

technical field [0001] The invention relates to a method for preparing a magnetic hollow double-shell imprinted adsorbent by using Pickering emulsion polymerization, which belongs to the technical field of preparation of environmental functional materials. Background technique [0002] Pyrethroids are synthetic analogs of the natural insecticide permethrin. Due to its high efficacy at low doses, pyrethroids are used in agriculture instead of organochlorine and organophosphorus insecticides. In recent years, pyrethroids have been found in surface water and sediments. Although compared with organochlorine and organophosphorus pesticides, pyrethroid pesticides exhibit relatively low toxicity to mammals. However, some studies have shown that pyrethroid insecticides may easily cause disturbance of consciousness and seizures, affect the human central nervous system, and are also suspected of having endocrine disrupting effects. Therefore, it is necessary to selectively remove p...
