英文摘要It had been reported that alumina nanoshell coating could be obtained on the external surface of various substrates in one-nanometer precision in aqueous solution. In this work, alumina nanoshell coated mesoporous silica microbeads (nanoAl(2)O(3)/mesoSiO(2)) were prepared with the similar method, and were successfully applied to inorganic anions separation. As the mass transfer speed is largely constrained in the mesopore compared with that on the open surface, it was found that a complete alumina nanoshell coating could be obtained within the mesopore until the five-time coating was carried out. After characterization by BET, SEM and FTIR, it was found that the obtained nanoAl(2)O(3)/mesoSiO(2) particles are smooth and well dispersed, and the mesopores are well reserved. In addition, the full coverage of nanoAl(2)O(3) shell in mesopores was also confirmed by the binding capacity experiments with berberine. Finally, the nanoAl(2)O(3)/mesoSiO(2) particles were packed in silica capillary for the separation of inorganic anions I-, SCN-, Br-, NO2- and NO3- with ion chromatography (IC), and a column efficiency of 3.8 x 10(4) plates per meter was obtained for I-.
