  • Silica Gel an overview | ScienceDirect Topics

    Silica gel, alumina, and kieselguhr are common stationary phases used in the separation of lipid mixtures by normalphase chromatography, with silica gel being the most widely used. Silica gel modified by chemically bonded ligands, such as octadecylsiloxanebonded groups, is suitable for reversedphase separations.

    orous inorganic silica membranes suitable for gas [6,13], vapor [14] or liquid separations [15]. Using EISA, the surface pores of the anodic alumina support are first filled with a mesoporous silica sublayer, thus reducing its surface pore size and facilitating deposition of a microporous gas separation membrane using spincoating.

  • EP0950020A1 Removal of silica from bauxite Google Patents

    A process for removing silica from bauxite is disclosed. The method includes the step of mixing bauxite with a caustic liquor to form a mixture and to dissolve and stabilise at least a substantial part of the reactive silica from the bauxite. The caustic liquor is selected to have a high caustic concentration and a high alumina content.

  • : Separation Theory Chemistry LibreTexts

    Aug 14, 2020· A compound that forms strong IMF's with the silica or alumina will often favor the stationary phase, and will spend much of the elution time adhered to the plate. This means it will spend less time in the mobile phase (which is the only means for it to travel up the plate), causing it to end up low on the TLC plate, and have a low \(R_f\).
