摘要
用静态吸附的实验方法对三种聚季铵型阳离子聚合物(COP)在蒙脱土上的吸附现象进行了研究,实验结果表明,COP在蒙脱土上的吸附等温线不符合Langmuir规律,而存在吸附最大值现象,用红外光谱法和岩芯流动试验方法也得到相同的结果。
The adsorption of three cationic organic polymers (COP) on montmorillonile was investigated by static adsorption method. Experiment results show that the adsorption isotherms of the COPs on montmorillonite do not conform with Langmuir model, but present the adsorption maximum, The same results were obtained by IR method and flow test of core.
