Structure of cobalt (II) perchlorate adsorbed on silica gel surface chemically modified with benzimidazole molecule
(1997-12-01)
Covalently attached benzimidazole molecules on silica gel surface, ≡SiL (where L = N-propyl-benzimidazole), adsorbs Co(ClO4)2 from non-aqueous solvent by forming a surface complex according to the reaction: m ≡SiL + Co(ClO4)2 ...

Production of silica gel from residual rice husk ash
(Sociedade Brasileira de Química, 2011)
This paper presents a study on the production of silica gel in hydrothermal process using residual rice husk ash. Measurements of the chemical composition, X-ray diffraction, infrared spectroscopy, particle size distribution, ...
Synthesis of ordered mesoporous SBA-3 materials using silica gel as silica source
(Elsevier Science, 2014-06)
Nanostructured materials have exceptional and highly attractive properties, including catalyst, adsorbent, separation media and chemo sensor. Technical advances in these fields require the development of ordered porous ...
Small angle X-ray scattering study of structural changes in silica gel modified with organofunctional groups
(1989-12-01)
Silica gel surfaces, organofunctionalized with 2-mercaptobenzimidazole, iminosalicylaldehyde and imidazole groups were examined using the small angle X-ray scattering technique (SAXS). From the scattering intensity data ...
