|Title:||Stability Of Layered Aluminum And Magnesium Organosilicates|
|Abstract:||New nanostructered layered inorganic-organic aluminum (Sil-Al) and magnesium (Sil-Mg) organosilicates - were prepared by a single step template sol-gel route under mild conditions, using a new alkoxysilane [(3-urea-dodecyl)propyl]triethoxysilane, containing embedded polar urea groups. The hybrids were characterized by elemental analysis, infrared spectroscopy, solid-state 29Si, 13C and 27Al nuclear magnetic resonance and X-ray diffraction. The XRD data showed that the magnesium hybrid material exhibits a lamellar structure similar to talc, a natural inorganic silicate. In order to employ these alternative sorbent materials for solid phase extraction applications, the chemical stability of the hybrids were investigated over a wide pH range varying from 2 to 12. © 2007 Elsevier Inc.
