Amino-modified high-surface-area radial-pore silica microspheres for efficient perfluorooctanoic acid removal
We report the synthesis of amino-modified radial-pore silica microspheres with large particle sizes of 1.6 μm and a high surface area of 1300 m<sup>2</sup> g<sup>-1</sup> for removal of PFOA from water. The microspheres achieve a maximum adsorption capacity of 775 mg g<sup>-1</sup>, a rapid equilibrium within 30 min, and 88.3% capacity retention after 5 cycles.
