In the present work, the tetrasulfide-functionalized silica (TFS) was prepared by a hydrothermal assisted grafting method for removing Pb(II) from aqueous solutions. The material was characterized by FT-IR, SEM, EDS and TGA. Adsorption isotherm and kinetics studies were carried out in batch adsorption experiments. The result showed that the adsorbent had a maximum adsorption capacity of 142.79mg/g...
