| 摘 要： | 考察了温度、pH、共存酸以及不同树脂对β-萘磺酸吸附的影响。平衡数据符合Langmuir等温线，获得的热力学数据表明过程是可行的。通过动力学实验，对过程的机理进行初步研究。研究表明，该法可有效地实现硫酸和β-萘磺酸的分离。

| Abstract: | The influence of temperature, pH, and co-existed acid, as well as dif ferent resins on the adsorption of NSA have been investigated. The adsorption da ta have been correlated with Langmuir adsorption model. Thermodynamic parameters obtained indicated the feasibility of the process, and kinetic studies provided the necessary mechanistic information of the removal process. H\-2SO\-4 and NSA acids may be efficiently separated in a column. |
