Abstrakt: The aflatoxin B1 (AFB1) adsorption properties of several lignins isolated by the Pepper's method from grassy plants: Helianthus tuberosus (LS-1), Atriplex patula (LS-2), Rhododendron tomentosum (LS-3), Althaea officinalis (LS-4), Lavatera (LS-5), and from wood of spruce Pícea (LS-6) were studied. The adsorption was conducted in vitro in the modeled conditions of the gastrointestinal tract. The correlations between the values of adsorption-desorption and the parameters of surface-porous structure and chemical structure of the lignins were established. The relationships between the adsorption capacity and properties of the lignins led us to the conclusion that chemisorption play the most important role in the strong adsorption of aflatoxin B1. The contribution of the surface physical properties to the process of adsorption of aflotoxin B1 was not significant. It was shown that the sample of lignin isolated from stems of Althaea officinalis, was characterized by the highest value of strong adsorption of aflatoxin B1.
