Abstract

The invention discloses a hydrophilic hyperbranched polyglycidyl ether anion magnetic adsorbent as well as a preparation method and application thereof, and belongs to the technical field of nano material preparation and food analysis application. The preparation method comprises the following steps: synthesizing magnetic nanoparticles Fe3O4 by adopting a solvothermal method; then synthesizing a solid polymer by taking the magnetic nanoparticles Fe3O4 as a carrier, polyglycidyl ether as a functional monomer and potassium methoxide and anhydrous tetrahydrofuran as solvents through anion ring-opening polymerization reaction; and finally, separating the solid polymer through an external magnetic field, and washing and drying the separated solid polymer to obtain the hydrophilic hyperbranchedpolyglycidyl ether anion magnetic adsorbent. The prepared hydrophilic hyperbranched polyglycidyl ether anion magnetic adsorbent is uniform in particle size, good in structural stability, strong in magnetic response, good in reusability, high in cochineal adsorption capacity, high in recovery rate, low in material cost and simple to prepare.

Description

technical field

[0001] The invention belongs to the technical field of nanomaterial preparation and food analysis application, and relates to a hydrophilic hyperbranched polyglycidyl ether anion magnetic adsorbent and a preparation method and application thereof. Background technique

[0002] Carmine (also known as carminic acid, carminic acid) is an anthraquinone natural pigment extracted from cochineal insects growing on cactus, which is only one word different from the synthetic pigment carmine. Carmine is the most widely used and large amount of monoazo artificial synthetic pigment in the world. It can be metabolized in the body to generate aromatic amine compounds, which can induce mutations by combining with DNA and RNA, and have certain carcinogenicity. The natural pigment cochineal is often used as an excellent colorant for food, cosmetics, medicine and textiles because of its stability, safety, and non-carcinogenic and teratogenic characteristics. However, the addi...
