阳离子双子表面活性剂凝聚相萃取分离甲基橙的研究
Study on cationic gemini surfactant coacervate phase for the extraction of methyl orange
-
摘要: 以季铵盐阳离子双子表面活性剂1,6-二(十二烷基二甲基)溴化二铵(12-6-12)、苯甲酸钠(NaBz)和羧甲基纤维素钠(NaCMC)为原料,构筑了两种微观结构不同的凝聚相,用于从水溶液中萃取分离阴离子染料甲基橙(MO)。结果表明:12-6-12/NaBz和12-6-12/NaBz/NaCMC凝聚相分别为蠕虫状胶束缠结网络结构和三维网络结构;两种凝聚相对阴离子染料MO都具有良好的萃取效果,且在与阳离子染料亚甲基蓝共存时,能选择性地萃取MO;萃取机制可能是在加入MO后,凝聚相中的部分MO分子通过苯环结构嵌入到12-6-12胶束内核,部分MO分子则吸附在12-6-12胶束表面参与网络结构凝聚相的形成。Abstract: Two coacervate phases with different microstructures were constructed with cationic quaternary ammonium gemini surfactant hexamethylene-1,6-bis(dodecyldimethylammonium bromide) (12-6-12), sodium benzoate (NaBz) and sodium carboxymethylcellulose (NaCMC), and the anionic dye methyl orange (MO) was extracted from aqueous solution. The experiments results showed that the coacervate phases of 12-6-12/NaBz and 12-6-12/NaBz/NaCMC were respectively worm-like micelle entanglement and three-dimensional network structure, and they had great efficiency in the extraction of MO from water. Moreover, the two coacervate phases could selectively extract anionic dye MO in the presence of cationic dye methylene blue. The possible extraction mechanism could be that after adding MO into the coacervate phase, some MO molecules were embedded into the 12-6-12 micellar core through the benzene ring structure, and some MO molecules were adsorbed on the 12-6-12 micellar surface, which participated in the formation of the coacervate phase with network structure.
