Annular rings with controllable sizes are successfully created on the surface of COOH-functionalized mesoporous silica (namely, XC-CAR-10, where X represents the number of carbons in the diamines used) for the adsorption of metal ions. In particular, excellent adsorption ability and selectivity towards Pb2+ (ca. 300 mu g mg(-1)) were achieved using 3C-CAR-10.
