Abstract:

Sorption materials based on N-2-sulfoethylchitosan (SECH) with various degrees of cross-linking by glutaric aldehyde were synthesized. The composition and structure of the materials were characterized by elemental analysis and IR Fourier spectroscopy. The selectivity coefficients K (Ag/Cu) were determined for sorbents with a degree of substitution equal to 0.5. It was shown that the sorption selectivity of silver(I) grows with increasing degree of SECH cross-linking, compared with copper(II) in an ammonia-acetate buffer solution.
