  • 摘要: 采用振荡实验方法,比较研究了2种非离子表面活性剂(Triton X-100和Tween80) 和2种阴离子表面活性剂(SDS和SDBS)对菲的最佳增溶振荡时间及其对菲的增溶能力,同时也比较分析了表面活性剂对菲的质量增溶比(WSR)与其亲水亲油平衡值(HLB)的关系.结果表明,Triton X-100、Tween 80、SDBS和SDS对菲的最佳增溶振荡时间分别为12、12、24和36 h.在表面活性剂临界胶束浓度(CMC)上下,4种表面活性剂对菲均具有增溶能力, 尤其表面活性剂浓度超过其临界胶束浓度(CMC)时,增溶效果更加明显.实验数据也表明4种表面活性剂对菲的增溶能力存在差异,即非离子表面活性剂对菲的增溶能力大于阴离子表面活性剂对其的增溶能力,具体表现为Triton X-100>Tween80>SDS>SDBS.该顺序与表面活性剂的HLB有关.
    Abstract: Surfactants can increase the solubility of hydrophobic organic compounds (HOC). They have been applied to areas such as soil washing, flushing and treatment of non-aqueous phase liquids(NAPLs). In this research, the ability of two nonionic surfactants (Triton X-100 and Tween80) and two anionic surfactants (SDS and SDBS) for phenanthrene solubilization was investigated by comparing their solubilization kinetics using agitated experimental method. The relationship between the weight solubility ratio (WSR) and hydrophile-lipophile balance value (HLB) of surfactants was also examined. The optimal solubilizing duration of agitation in Triton X-100, Tween80, SDBS and SDS for phenanthrene was 12, 12, 24 and 36 h, respectively. Solubility enhancement for phenanthrene by the four surfactants was observed either above the critical miceller concentration (CMC) or below it. Especially, the solubilization was increased significantly above the CMC.The experimental data obtained also showed some differences among the four surfactants, and indicated that the solubilization ability of the nonionic surfactants was much higher than the anionic surfactants. The order of solubility enhancement was Triton X-100>Tween80>SDS>SDBS. This order is related to HLB of the surfactants.
