The data about the chemical structure of the polymers, synthesized by the method of fermentative dehydropolymerization of ferulic acid, and also coniferyl alcohol, are presented. It is established that the polyferulic acids have practically identical element composition, but they differ, according to data of IR- and NMR-13C-spectroscopy, in the quantitative content of phenol and carboxyl groups. A study of their adsorptivity with respect to zearalenone mycotoxin is carried out, and the characteristics of specific surface area and capillary-porous structure are established. The calculations of the correlation relationships between the adsorptivity and the parameters of surface-porous structure and chemical structure of different models indicate to the key role of the mechanisms of chemical adsorption, whereas the contribution of physical phenomena is not essential. It is shown that the polymer, synthesized from the coniferyl alcohol, is characterized by the highest indices of adsorption.
