MAGNETIC CORE-SHELL NANOSPHERE FOR ADSORPTION OF PHENOLIC POLLUTANT, PREPARATION METHOD, AND APPLICATION

WIPO Patent Application WO/2022/174551

A1

The present invention provides a magnetic core-shell nanosphere for the adsorption of a phenolic pollutant, a preparation method, and an application. The preparation method comprises the following steps: preparing a nanoscale adsorption carrier; performing a first round of modification on the nanoscale adsorption carrier, and obtaining a first modified adsorption carrier; performing a second round of modification on the first modified adsorption carrier, and obtaining a second modified adsorption carrier; and performing a polymerization reaction on the second modified adsorption carrier, and obtaining a magnetic core-shell nanosphere. The present invention solves the problem where only one round of modification on a magnetic nanoparticle is performed in current preparation processes for magnetic porous adsorbents, so if the magnetic adsorbent performs adsorption in a high temperature environment, the miscibility of the magnetic nanoparticle and a polymer will be destroyed, thereby affecting the adsorption function of the magnetic adsorbent.
