Porous silica. Silica is commercially available in bead form (Pora-sil Merck-O-Gel Si) with a range of porosities. This is an aerogel, with a very rigid structure. It can be used in some organic solvents, but it is best used in water. It is rather highly polar, and can tend to retard polar molecules by adsorption. [Pg.150]
