摘要
根据表面活性剂的种类,将表面活性剂改性膨润土分为单阳离子有机膨润土、双阳离子有机膨润土、阴离子有机膨润土、阴-阳离子有机膨润土和非离子有机膨润土等5类;并对近几年来所研究的表面活性剂对膨润土改性的各种实验方法以及对改性膨润土所采用的表征手段、各类改性后膨润土的特征与吸附规律及应用进行了评述;同时展望了其未来可能的发展方向。
Surfactant modified betonites can be classified in accordance with the surfactant used for the modification, as five categories of organo - bentonite namely cationic, anionic, nonionic, dual - cationic and cationic - anionic. Various test methods for the study of modifying bentonite with surfactants, characterization means of the modified bentonites, as well as the features and adsorption mechanism of various modified betonites were reviewed. The future forecast for the development of this material was described.
