The good dispersion comes from the stable film existing in the interface. The important factors influencing the stability of the monomolecular film were CMC〓 and CMC〓. Great values of CMC〓 and CMC〓 can produce better film (with good stability in the interface).

而影响表面活性剂分子在界面上存在稳定性的主要因素是CMC〓和CMC〓，CMC〓和CMC〓的协同作用是影响分散体系中表面活性剂性能发挥的关键，也是评价表面活性剂性能优劣的工具。

The XRD analysis revealed that the relative pure nickel metal products with an average size of 12.6 nm could be obtained using PVA as surfactant, a mixture of nickel and nickel sesquioxide products with an average size of 25 nm was obtained using DTAB as surfactant.

结果表明：以PVA作表面活性剂得到相对纯的纳米镍粉，平均粒径约为12.6nm；而以DTAB为表面活性剂得到镍和三氧化二镍的混合物，平均粒径约为25nm；采用PVA为表面活性剂在产品的纯度和粒度上都优于DTAB。

Different mechanisms and model of the sorption of organic compounds by soli /sediment in combined polluted environment were reviewed, including many factors which influence the sorption.

本文评述了复合污染中有机物在土壤/沉积物上的吸附机理及影响吸附的主要因素，主要论述了共存物质及环境条件对有机物吸附行为的影响，同时，总结了表面活性剂在土壤/沉积物上的吸附机理和吸附模型，探讨了影响表面活性剂吸附的因素，评述了表面活性剂对有机物在土壤/沉积物上吸附行为的影响及机理。

The category of surfactant and the action of it in the wastepaper deinking was introduced.

综述了表面活性剂的性质及分类，以及表面活性剂在废纸脱墨各阶段的作用，并对以后脱墨用表面活性剂的发展趋势提出了一些看法。

The intermixture of positive ion surfactant Cetyltrimethyl Ammonium Bromide and zwitterion surfactant N,N-C12BE was used to modify the natural zeolite. Correlative parameters of modified zeolite adsorbing Cr and phenol from wastewater were studied.

摘 要：用阳离子表面活性剂十六烷基三甲基溴化铵与两性离子表面活性剂 N，N-二甲基十二烷基甜菜碱复配的混合表面活性剂对天然沸石改性，研究了改性沸石吸附废水中 Cr 和苯酚的相关参数。

The encapsulated TiO〓 particles by polymer were obtained with soapless emulsion polymerization of methyl methacrylate in water in the presence of the pretreated TiO〓 particles.

一种是用偶联剂钛酸丁酯对亲水性TiO〓粒子进行预处理，钛酸丁酯与TiO〓表面羟基反应，交联到TiO〓粒子表面，使TiO〓粒子表面由亲水性转变为憎水性，改善无机粉体与有机单体的亲合性，再进行TiO〓存在下甲基丙烯酸甲酯的无皂乳液聚合，即可得到TiO〓-PMMA复合粒子：另一种方法是用表面活性剂对TiO〓进行预处理，再进行TiO〓粒子存在下甲基丙烯酸甲酯的无皂乳液聚合，TiO〓粒子表面可形成一层均匀的聚合物膜，提出了包覆机理，指出单体在无机粉体表面发生聚合的关键是预先在粒子表面形成聚合场所，即吸附一层表面活性剂。
