Superparamagnetic microspheres with an Fe3O4@SiO2 core and a perpendicularly aligned mesoporous SiO2 shell were synthesized through a surfactant-templating sol-gel approach. The microspheres possess high magnetization (53.3 emu/g), high surface area (365 m2/g), large pore volume (0.29 cm3/g), and uniform mesopore (2.3 nm). By using the unique core-shell microspheres with accessible large pores and excellent magnetic property, a fast removal of microcystins with high efficiency (>95%) can be achieved.
通过表面活性剂模板溶胶-凝胶法合成了具有Fe3O4@SiO2核和垂直排列的介孔SiO2壳的超顺磁性微球。这些微球具有高磁化强度（53.3 emu/g）、高比表面积（365 m2/g）、大孔体积（0.29 cm3/g）和均匀的介孔（2.3 nm）。通过使用具有可及大孔和优异磁性的独特核壳微球，可以高效（>95%）快速去除微囊藻毒素。
