摘要
本文研究了以大孔树脂XAD-2为吸附剂的十种有代表性的芳族化合物的动态吸附特征。这十种化合物划分为三个体系,即苯环上带有吸电子基团的体系、苯环上带有推电子基团的体系及稠环体系。文章全面地分析了三个体系中影响吸附性能的共同因素和不同体系的各自特点,然后以实验结果和Freundlich 方程为基础,通过数据处理建立了三套经验模型,模型的计算值接近于实验值。
Our work describes the kinetic adsorption features of ten armatic comp-ounds on the macroporous resins XAD-2 by the column technique.The tencompounds are divided into three systems according to the nature of substit-uents and the size of armatic rings,they are the system with electronwithdrawing groups,the system possessing electron donating groups,andthe system of fused ring.Authors summarise the common factors controllingadsorption capacities of the ten compounds and analyse the characteristics ofeach system in detail.On the basis of experimental results and freundlichequation,three empircal models are esteblished after data handling.Theresults from empircal equations approximate to the data from experiments.
