Interface Chemistry of Nanostructured Materials: Ion Adsorption on Mesoporous Alumina

“…Uncalcined mesoporous silicate materials synthesized with hexadecyltrimethylammonium bromide as a template are able to remove significant amounts of trichlorethylene and tetrachloroethylene from water (9), while calcined mesoporous silicates or titanosilicates were found to have the capability to remove copper, lead, and uranyl ions from aqueous solutions (10)(11)(12). Furthermore, an ordered mesoporous anion-exchange inorganic/organic hybrid resin has been suggested for radionuclide separation (13).…”

Mesoporous Transition Metal Oxide Ceramics

“…Ju et al prepared ordered anion-exchange hybrid mesoporous silicas for thorium uptake from process waste streams [154]. The thorium adsorption was to be far more selective in the hybrid mesoporous material compared to a popular organic commercial anion-exchange resin containing quaternary ammonium.…”

Mesoporous silica (KIT-6) derivatized with hydroxyquinoline functionalities as a selective adsorbent of uranium(VI)

“…Among them, the development of functionalized mesoporous materials for adsorption applications including the removal of radionuclides [10], heavy metal ions [11][12][13][14][15][16][17][18], dyes, organics, and anionic complexes, has generated considerable interest. In many adsorption applications, the preparation of efficient adsorbents for heavy metal ions by the grafting ligands into mesostructured oxides is clearly one of the most promising methods for environmental clean-up applications and many reports can be found in literature since the seminal reports [19,20].…”
