摘要/Abstract

摘要： 探讨不同温度下甲壳胺纤维对含有6个磺酸基的直接橙39的吸附性能,运用3种吸附理论模型即Langmuir、Freundlich和Redlich-Peterson吸附方程对实验数据进行拟合,对获得的3种理论吸附模型的吸附参数及正规偏差(ND)进行比较。结果表明不同温度下,Freundlich吸附模型偏离实验点的程度较大,而Redlich-Peterson吸附模型最符合甲壳胺纤维对直接橙39的吸附行为,同时伴有吸热现象出现。

Abstract: Adsorption of Direct Orange 39 with six sulfonic groups on chitosan fibers at different temperatures was investigated. The experimental data were analyzed and correlated with three kinds of adsorption isotherm model, namely, Langmuir, Freundlich and Redlich-Peterson. Analytical comparison of the adsorption parameters of different models and normalized deviation from the experimental showed that Freundlich isotherm exhibited more deviation from the experimental data and Redlich-Peterson isotherm fitted the best to describe the adsorption behavior of Direct Orange 39 on chitosan fibers, and adsorption is endothermic.
