Wheat Germ Lectin Sorption by Chitosan Polyelectrolyte Complexes

The possible application of polyelectrolyte complexes (PEC) of chitosan and copolymers of maleic acid with N-vinylpyrrolidone, styrene, and ethylene and/or cross-linked chitin sorbents (CLCS) synthesized on the basis of PEC for sorption of wheat germ lectin (WGL) was studied. The synthesis of spherically granulated sorbents was shown. Compared to unmodified chitosan, there was a significant increase in sorption capacity of WGL by the sorbents: PEC, 2.5-fold, and CLCS, from 3.5-fold to 7-fold.
