Abstract

The study of ion sorption of Cu²⁺ on fungi isolated from mycelium Aspergillus niger chitin- and chitosanglucan complexes showed that these biopolymers have a fairly high sorption ability. As a result of mathematical modeling found that the theoretical models of Langmuir, Freundlich and Temkin are adequate, with a high coefficient of determination (R² = 0.97–0.99) describe equilibrium sorption of Cu²⁺ on the studied biocomplexes. An analysis of the sorption parameters obtained from the regression equation shows that the mechanism of sorption of Cu²⁺ on chitin- and chitosan-containing complexes has a more complex character that differs from the theoretical premises of classical theories and, presumably, is based on the processes of ion exchange and complexation.

真菌黑曲霉菌丝分离的甲壳质和壳聚糖生物复合物上铜离子（Cu 2+）吸附过程的数学模型

摘要

Cu ²⁺在黑曲霉菌丝质壳聚糖和壳聚糖复合物中分离的真菌上的离子吸附研究表明，这些生物聚合物具有相当高的吸附能力。数学建模的结果表明，Langmuir，Freundlich和Temkin的理论模型是足够的，具有较高的测定系数（R ² = 0.97–0.99）描述了在研究的生物络合物上Cu ^2+的平衡吸附。从回归方程获得的吸附参数的分析表明，Cu ²⁺的吸附机理 含有几丁质和壳聚糖的复合物的“特征”具有更复杂的特征，这不同于经典理论的理论前提，并且推测是基于离子交换和络合的过程。
