有机膨润土的制备及其吸附性能的研究

Study on Preparation of Organic Bentonites and Their Adsorbability

用阳离子表面活性剂作改性剂,通过阳离子交换法对膨润土进行有机改性制得有机膨润土。考察了膨润土类型、阳离子交换容量、改性剂的用量、改性剂的化学性质对有机膨润土吸附性能的影响。还考察了有机膨润土的再吸附性能。

The organic bentonites were prepared by the organic modification to bentonites by cation exchange process using cationic surfactant as modifier. The effects of bentonite type, cation exchange capacity, amounts of cationic surfactant as modifier, and chemical properties of the modifiers on adsorbability of the organic bentonites were investigated.
