Abstract

A preparation method for a Fe3O4@MoF-199@C18 nanocomposite comprises the following steps of: 1, preparing Fe3O4 nanoparticles from FeCl3.6H2O, ethylene glycol and sodium acetate; 2, preparing Fe3O4@MoF-199 from 1,3,5-benzenetricarboxylic acid, N,N-dimethylformamide, ethyl alcohol, the prepared Fe3O4 nanoparticles and triethylamine; and 3, preparing the Fe3O4@MoF-199@C18 nanocomposite from chloro(dimethyl)octadecylsilane and the Fe3O4@MoF-199. The preparation method for a Fe3O4@MoF-199@C18 nanocomposite is simple to operate, and low in cost; the Fe3O4@MoF-199@C18 nanocomposite prepared thereby has a particle size at the scale of nanometer, and has the advantages of uniform particles, easiness for separation and collection, good dispersibility, and high adsorption capacity; the nanocomposite can not cause pollution to the environment during preparation and is harmless to the health of an operator.

Description

technical field [0001] The invention relates to a method for preparing a metal-organic framework composite material, in particular to a magnetic metal-organic framework nanocomposite material (Fe 3 o 4 @MOF-199@C18) preparation method. Background technique [0002] There are many methods for the synthesis of metal-organic framework materials, and the common methods include hydrothermal method, diffusion method, microwave-assisted method, room temperature stirring method, ultrasonic-assisted method and so on. [0003] (1) Hydrothermal method [0004] The hydrothermal method (also known as the hydrothermal method) refers to a method in which water is used as a solvent to react the reactants through high temperature and high pressure under airtight conditions to cultivate crystals. So far, the reaction method of the hydrothermal method is not limited to using water as a solvent, and may be part or all of an organic solvent during the reaction, that is, the so-called hot solv...
