中文摘要：

戊二醛作交联剂，在壳聚糖分子链中引入了β-环糊精的疏水空腔结构，制备出壳聚糖交联β-环糊精高聚物（CTS-CD）。以酸性红B为例，研究了CTS—CD对酸性染料的吸附动力学和热力学特性。298K，CTS-CD对酸性红B的饱和吸附容量高达661．4mg／g，起始浓度363．2mg／L，吸附△H=80．3kJ／mol、△S=323．3J／（mol·K）、△G=-16．1kJ／mol，Ea=11．72kJ／mol。室温下，吸附过程可用一级吸附动力学方程来描述，符合Langmuir等温吸附模型。CTS-CD可作为吸附材料用于治理染料、印染废水。

英文摘要：

In this paper, chitosan-β-cyclodextrin （CTS-CD）, a kind of high polymer, was synthesized by immobilizing the β-cyclodextrin （β-CD） onto the molecular structure of chitosan by the cross-linking function of glutaraldehyde. The adsorption kinetic and thermodynamic characteristics of acid dyes on CTS-CD were studied by taking the Acid Red B as an example. At 298K, the saturated adsorption capacity of CTS-CD for Acid Acid B was 661.4mg/g. When the initial concentration of Acid Red B was 363.2mg/L, the enthatpy change （△H）, the entropy change （△S）, the Gibbs free energy change （△G） and the apparent activation energy of the adsorption were 80.3, 323.3, -16.1 and 11.72kJ/mol, respectively. At room temperature, the adsorption of CTS-CD for contaminants followed Langmuir adsorption equation and the first-order kinetic equation. As an adsorption material, CTS-CD can be used to remove acid dyes from industrial wastewater.
