摘要

文章论述了通过对甲壳素和壳聚糖链上的 OH 和 NH2 基团进行羧甲基化处理，从咸海甲壳类 Parthenogenetica 蒿属甲壳动物的包囊中合成甲壳素和壳聚糖的水溶性衍生物。研究了羧甲基甲壳素和羧甲基壳聚糖在尺寸排阻液相色谱法中的洗脱、粘度和聚电解质特性。使用浓度为 0.1 摩尔/升的硝酸钠水溶液作为洗脱液，抑制了静电效应，并实现了这些多糖的排阻分离机制。

Exclusion liquid chromatography of carboxymethylchitin and carboxymethylchitosan from crustacean Artemia Parthenogenetica of the Aral Sea

The article deals with the synthesis of water-soluble derivatives of chitin and chitosan from cysts of crustaceans of the genus Artemia Parthenogenetica of the Aral Sea by carboxymethylation of OH and NH2 groups of their chains. The elution, viscosity and polyelectrolyte properties in size exclusion liquid chromatography of carboxymethylchitin and carboxymethylchitosan were studied. The suppression of electrostatic effects and the implementation of the exclusion mechanism for the separation of these polysaccharides were achieved by using an aqueous solution of sodium nitrate with a concentration of 0.1 mol/l as an eluent, which was recommended for determining molecular weight characteristics.
