Size-adjustable annular ring-functionalized mesoporous silica as effective and selective adsorbents for heavy metal ions

Annular rings with controllable sizes are successfully created on the surface of COOH-functionalized mesoporous silica (namely, XC-CAR-10, where Xrepresents the number of carbons in the diamines used) for the adsorption of metal ions. In particular, excellent adsorption ability and selectivity towar...

Zusammenfassung:Annular rings with controllable sizes are successfully created on the surface of COOH-functionalized mesoporous silica (namely, XC-CAR-10, where Xrepresents the number of carbons in the diamines used) for the adsorption of metal ions. In particular, excellent adsorption ability and selectivity towards Pb super(2+) (ca.300 mu g mg super(-1)) were achieved using 3C-CAR-10.
