This study focused on the preparation of phosphonic acid-functionalized hollow mesoporous silica spheres (PHMSs) and their adsorption performance of trace antimony(III) from water under room temperature. Firstly, monodisperse carbon microspheres (CS) synthesized by the glucose-oxygen hydrothermal method was used as the hard template, and cetyltrimethylammonium bromide as the soft template to synthesize hollow mesoporous silica spheres (HMSs). Then, phosphate groups were grafted by the post-grafting method to synthesize PHMSs. The characterizati...
