A method for preparing silica nanoparticles, the method comprising: adding centrimonium bromide (CTAB) to a water and ethanol to create a first reaction mixture; adding NH4OH to the reaction mixture to create a second reaction mixture; adding a first amount of tetraethyl orthosilicate (TEOS) to the second reaction mixture to create a third reaction mixture; adding ethylenediaminetetraacetic acid (EDTA) to the third reaction mixture then adding a second amount of TEOS to create a fourth reaction mixture; obtaining formed silica spheres; separating the formed silica spheres; washing the formed silica spheres with water and ethanol; and drying the formed silica spheres in an oven for at least about 8 hours to obtain silica nanoparticles.

Functionalized silica nanoparticles for lead adsorption

Amino-rich anionic mesoporous silica (AMS) nanoparticles prepared through adding two different types of co-structuring directing agent (CSDA) molecules, thus increasing the amino amount within the AMS together with preserving ordered porous structure. Further boosting of amino amount can be accomplished through linking three different CSDA molecules together. Amino-functionalized mesoporous silica can be obtained with high amino amounts with linking either double or triple CSDA molecules while preserving ordered mesoporous structure and high textural properties.
