    Abstract

    The effects of salt concentration on multiple-point adsorption of target molecules by heteropolymer gel were analyzed. Positively charged adsorber monomers contained in the gel can interact electrostatically with negatively charged groups on the target molecules. The adsorption of the targets was found to depend on the salt concentration. A slight increase in the salt concentration decreased the adsorption affinity by several orders of magnitude.
