阳非离子有机膨润土对水中三唑酮的吸附

摘要

膨润土廉价易得且有很强的吸附性能，用各种表面活性剂与膨润土制取有机膨润土的技术已经比较成熟。该文对有机膨润土吸附水中三唑酮进行了研究。结果表明吸附等温曲线呈线性，主要为分配作用，吸附作用的大小由有机膨润土中有机碳的含量决定，并与表面活性剂的种类、组成及配比有关；阳非离子有机膨润土有机碳含量最高，其对水中三唑酮的吸附能力也最强，有望成为水体或废水中有机农药甚至其他有机污染物去除的新技术。%Nobentonite is cheap and easy to prepare with strong adsorption. The technology of preparation of organobentonite is relatively mature now. The absorption properties and mechanisms of triadimefon with organobentonite were studied. The results indicate that the absorption isotherms of triadimefon with cationic-nonionic organobentonite are linear,which is mainly due to distribution effects. The magnitude of distribution effects is decided by the organic carbon contents in organobentonite,species and composing of surfactant. Absorption ability of triadimefon with cationic-nonionic organobentonite in water is the strongest with the highest organic carbon content. Cationic-nonionic organobentonite is expected to be a new technology to remove organic pesticides and other organic pollutant.
