摘要

本研究旨在制备三种天然吸附剂:粗甲壳素、壳聚糖和壳聚糖,研究合成废水中氯化物的去除。根据Freundlich和Langmuir模型的线性化方法,描述了氯化物在这些载体上的吸附过程。研究了一些理化参数对脱氯过程的影响。为了接近水脱氯的条件,我们也有兴趣研究反离子的存在对壳聚糖去除氯离子能力的影响。此外,我们还寻找了使用碱性溶液解吸的最佳条件。

Study of dechlorination by natural adsorbents (chitin and chitosan)
This study aim to the preparation of three adsorbent natural materials: crude chitin, chitin and chitosan extracted from shellfish, to study the elimination of Chlorides from a synthetic effluent. The process of adsorption of chlorides on these supports is described following the linearized method of the model described by Freundlich and Langmuir. The study of the influence of some physico-chemical parameters on the dechlorination process has been undertaken.And in order to approach the conditions of water dechlorination, we were also interested in the study of the influence of the presence of the counter-ions on the ability to remove chloride ions on chitosan. Moreover, we looked for the optimal conditions of desorption using a basic solution.
