Porous glasses with controlled porosity

Section 1 considers the methods of synthesis and physico-chemical properties of new types of inorganic sorbents (complex carbon-mineral sorbents, co-precipitated hydroxides, functional polysiloxane sorbents, porous glasses with controlled porosity, colloidal silicas, aluminium oxyhydroxide colloids, apatites). These sorbents are widely used in scientific investigations, in chemical practice and are important from a technological point of view. The presented results provide additional possibilities for the preparation of inorganic sorbents possessing unique adsorption and catalytic properties. Moreover, Section 1 presents the possibilities of the computational studies on the design of synthetic materials for selective adsorption of different substances. 

One of the most important requirements for the GPC column is the absence of the specific interactions with the studied polymer. The more inert the surface of the packing material, the better. Early applications of GPC separation were sometimes performed on porous glass particles with controlled porosity [9]. The ease of the manufacturing of the controlled porosity particles had determined this choice, but it was not always possible to find an... 

The characteristic feature of controlled porosity glasses is a very narrow pore size distribution [2,3,5,16], well seen when compared with silica gel or other porous materials produced by polymerization or by crosslinking of monomers-cf. Fig. 5.
