摘要

研究了 AV-17-2P 阴离子交换器对不同成分溶液中色氨酸的非交换性吸附。研究表明，氨基酸的吸附与伴随成分的性质无关。量子化学模型对此做出了解释，它给出了盐形式的高碱性阴离子交换剂对色氨酸进行非交换吸附时，吸附剂相中形成的键的附着和能量特征的变体。极性相互作用起了主要作用，而π-π相互作用在氨基酸对高碱性芳香阴离子交换剂的非交换吸附过程中产生了额外的影响。

Some Features of Non-Exchangeable Sorption of Tryptophan: The Role of Polar and π–π Interactions

The non-exchangeable sorption of tryptophan by the AV-17-2P anion exchanger from solutions of different compositions was studied. The sorption of the amino acid was shown to be independent of the nature of the accompanying component. This was explained by quantum-chemical modeling, which gave variants of attachment and energy characteristics of the bonds formed in the sorbent phase during non-exchangeable sorption of tryptophan by a highly basic anion exchanger in the salt form. The polar interactions play the major role, and π–π interactions produce an additional effect during the non-exchangeable sorption of amino acids on highly basic aromatic anion exchangers.
