Abstract

The invention provides a preparation method of carboxymethyl-beta-cyclodextrin functionalized magnetic mesoporous silicon microspheres. The method includes the steps of: 1) preparing Fe3O4 via a coprecipitation method; 2) preparing SiO2-coated Fe3O4 particles (Fe3O4@SiO2), namely, magnetic silicon; 3) preparing mesoporous SiO2-coated Fe3O4@SiO2 particles (Fe3O4@SiO2@SiO2), namely, magnetic mesoporous silicon; 4) preparing carboxymethyl-beta-cyclodextrin (CM-beta-CD) via a wet process or a dry process; 5) preparing carboxymethyl-beta-cyclodextrin functionalized magnetic mesoporous silicon microspheres (Fe3O4@SiO2@SiO2-CM-beta-CD). In the invention, with Fe3O4 as an object, the functionalized magnetic mesoporous silicon microspheres are prepared through the coprecipitation method and Stobermethod, so that the method has simple processes and high-effective treatment, is low in cost, and supplies a new idea to preparation and application of magnetic adsorption microspheres. The product can improve effect of removing heavy metals in water by Fe3O4.

Description

technical field

[0001] The invention relates to the technical field of manufacturing new materials for water treatment, in particular to a preparation method of carboxymethyl-β-cyclodextrin functionalized magnetic mesoporous silicon microspheres. Background technique

[0002] Fe 3 o 4 Magnetic nanoparticles have the excellent properties of nanomaterials (such as small particle size, large surface area, etc.), and also have their own characteristics. When the particle size is less than 20nm, they exhibit superparamagnetism at room temperature; Modification, can have specific affinity adsorption with the target, and can quickly separate the target from the multi-component environment under the directional control of the external magnetic field; it has the advantages of simple preparation process, low price, low toxicity, structure and function The advantages of strong predictability and controllability make it have high application value in adsorption separation, catalysis a...
