摘要
用流动重量法测定了凹土（ＡＴⅡ）及凹土吸附干燥剂（ＡＴＭⅡ）对水的吸附平衡和吸附动力学性能。二样品的吸附等温线皆属类型Ⅱ，它们是水以不同吸附方式迭加的结果，经分解可用Ｌａｎｇｍｕｉｒ和ＢＥＴ方程拟合。吸附动力学曲线可用单孔模型Ｃｒａｎｋ方程很好地拟合。
The water adsorption equilibrium and adsorption kinetics of Attapulgite (ATⅡ) and its desiccant (ATMⅡ) have been determined by the flow weight method. The effects of temperature and concentration on adsorption equilibrium and rate have been studied. The adsorption isotherms of the two samples belong to type Ⅱ, and can be described by the combination of Langmuir eq. and BET eq.. The adsorption kinetic curve can be fitted by Crank eq.. The obtained results can be used for the application of ATMⅡ.
