摘要
综述了膨润土的基本概况,膨润土的有机改性原理与方法。有机膨润土在造纸工业中可用作助留助滤剂;与CPAM组成微粒助留体系,用作吸附剂处理造纸黑液、造纸过程中的树脂,处理印染废水以及含芳香类化合物、重金属离子、硫氰根离子和有机农药等的工业废水,并对这些领域中的应用前景作了展望。
The paper reviewed the basic knowledges of bentonite, modification principle and process of organobentonite. Organobentonite may be used as microparticulate retention and drainage aid together with CPAM. It was also used as adsorbents to treat black liquid of pulpmaking, control pitch in papermaking process, treat waste waters of printing and dyeing as well as other industry waste waters containing aromatic hydrocarbon, heavy metal ion, thiocyanate ion and organic pesticide. This paper also described the potential application in the field.
