Macromolecular core-shell structure microsphere as well as preparation method and application thereof

The invention provides a high-molecular core-shell structure microsphere as well as a preparation method and application thereof. The high-molecular core-shell structure microsphere comprises a polydivinylbenzene inner core and an outer shell which coats the outer part of the polydivinylbenzene inner core and is loaded with pyridine groups on the surface. The core particles of the microspheres are high in crosslinking degree, low in water swelling rate and high in structural strength, the shell crosslinking degree is low, the functional group density is high, trapping of hexavalent chromium ions is shell adsorption, and the adsorption response speed is high. 本申请提出一种高分子核壳结构微球及其制备方法和应用，其中高分子核壳结构微球包括聚二乙烯苯内核和包覆在所述聚二乙烯苯内核外部的表面负载有吡啶基团的外壳。该微球核粒子的交联度高、水溶胀率低、结构强度大，壳层交联度较低、功能基密度大，对六价铬离子的捕集为壳层吸附，吸附响应速度快。
