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。
