Kinetic peculiarities of sorbtion of compounds of glucouside and peptid structure on hypercrosslinkedsorbent MN-200

Abstract

Comparative assessment of the sorption capacity of macroporous polymer hydrophobic structure
with respect to the compounds of the triterpenic (saponin) and protein nature (amylase) was carried out. The
influence of the structural features of these substances in their sorption characteristics was examined. It is
shown that the decisive role in the formation of such macromolecular structures is playedby intermolecular
interactions, the nature and strength of which depends on the presence of functional groups, and the
stoichiometry of the sorbates. With the help of graphical method the limiting stage of sorption saponin and
amylase on the sorbent MN-200 is set. The diffusion coefficients of the compounds, the order of which is 10­
8 cm2 / s, which corresponds to the diffusion coefficient of adsorbed organic molecules cited in the literature
are counted
