Preparation method of imprinted carbon microspheres

Abstract

The invention relates to a preparation method of imprinted carbon microspheres. The imprinted carbon microspheres are prepared by a three-neck flask, an ultrasonic dispersion instrument, a water bath tub, an electric heating stirring utensil and an ultraviolet light mercury lamp, and the preparation method comprises the following steps of: firstly performing oxidation treatment on the carbon microspheres, then performing surface modification and further grafting a polymer on the surfaces of the carbon microspheres to finally prepare the imprinted carbon microspheres, wherein irregular cavity imprints are formed on the surfaces of the carbon microspheres. The preparation method has the advantages of advanced and reasonable process, short process flow, low environmental pollution, good product morphology, high purity which can be up to 99% and high product yield which can be up to 93%, the imprinted carbon microspheres are black and circular particles, the diameter of the particles is 100-200nm, and the imprinted carbon microspheres can be matched with a variety of chemical substances, so that the preparation method is a very ideal method for preparing the imprinted carbon microspheres, and products can be applied to a variety of industrial fields, such as pharmacy, fine chemicals and the like.

Description

technical field [0001] The invention relates to a method for preparing imprinted carbon microspheres, which belongs to the technical field of organic carbon material-carbon microsphere surface functional modification and application. Background technique [0002] Molecularly imprinted polymer is a new type of separation material developed in recent years. It is composed of template molecules to be separated and polymerizable functional monomers to form host-guest complexes through ionic interactions, hydrogen bonds, hydrophobic interactions, and supramolecular interactions. It is prepared by adding a cross-linking agent to polymerize; after the template molecule is removed, a cavity that matches the spatial structure of the template molecule is left in the polymer, and the functional group in the cavity has a specific binding ability to the template molecule; due to molecular imprinting Polymers have specific recognition ability and specific selection performance, and have s...

Problems solved by technology

[0003] The matrix of molecularly imprinted materials can be inorganic materials, such as silica gel, alumina, etc., or polymer materials, but the recognition sites of polymer microspheres are mostly inside the polymer microspheres. When recognizing larger molecules, the existence of diffusion resistance It will make it difficult for the molecule to be recognized to bind to the recognition site
