通过物理浸渍法利用有机胺（聚乙烯亚胺）对膨润土进行改性，然后利用X射线衍射、N2吸附脱附实验、元素分析等手段对膨润土改性前后材料的物理化学属性进行表征，最后考察了材料对CO2气体的吸附性能。结果表明，利用有机胺对膨润土进行改性后，材料对 CO2气体的吸附量明显增加（从6 mg/g 增至47 mg/g），且在循环使用中材料的稳定性良好。

Bentonite was modified by an organic amine ( polyethylenimine ) through a physical impregnation meth-od .Physical and chemical properties of samples were characterized by X-ray diffraction ( XRD) , N2 adsorption-desorp-tion measurement , and elemental analysis .CO2 adsorption performances of samples were finally investigated .It was demonstrated that CO 2 adsorption capacity of bentonite was significantly improved after amine modification from 6 mg/g to 47 mg/g.Furthermore, the amine-modified bentonite was very stable in the cyclic CO 2 adsorption-desorption ex-periments .
