| 摘 要： | 利用静态吸附实验方法,研究了有机改性凹凸棒石吸附活性艳蓝KN-R的热力学性质.在实验范围内,有机改性凹凸棒石对水中活性艳蓝KN-R的吸附平衡数据符合Freund lich吸附等温方程.研究结果表明:吸附焓变为正值,表明该吸附过程是吸热的,升高温度有利于吸附.吸附自由能为负值,表明该过程是常温下可以自发进行的.

| Abstract: | By using passive absorption method,it was studied that the thermodynamic properties of the absorption of organic modified palygorskite on reactive brilliant blue KN-R.Equilibrium data for the adsorption of KN-R onto organic modified palygorskite within the rang were obtained and correlated with Freundlich-type isotherm equations.The results indicated that the absorption process was endothermic,and the temperature is conducive to increased absorption.Free energy absorption was negative,indicated that the pro... |
