摘要

目的:研究弱碱性树脂对废水中5-氨基-2-氯甲苯-4-磺酸(CLT)和氯酸(HC1)的吸附性能。方法:对其进行动力学和等温线研究。计算并讨论了吸附酸的热力学参数。结果:CLT和HC1酸的吸附符合Langmuir等温线和一级动力学模型。结论:两种酸对D301R的吸附亲和力顺序为CLT酸> HCl酸。CLT酸和HCl酸可以分离。

Removal of 5-amino-2-chlorotoluene-4-sulfonic and chlorhydric acids from wastewater by weakly basic resin: equilibrium and kinetics.

Objective: To study the adsorption of 5-Amino-2-chlorotoluene-4-sulfonic (CLT) and chlorhydric (HC1) acids from wastewater by weakly basic resin.

Methods: The kinetics and isotherm were studied. Thermodynamic parameters for the adsorption of acids were calculated and discussed.

Results: The adsorption of CLT and HC1 acids followed Langmuir isotherm and the first-order kinetics model.

Conclusion: The adsorptive affinity of the two acids on D301R is in the order of CLT acid > HCl acid. CLT and HCl acids can be separated.
