中文摘要：
考察不同类型的表面活性剂对三氯乙烯（TCE）的增溶作用.选用阴离子型十二烷基硫酸钠（SDS）、非离子型聚氧乙烯辛基苯酚醚（TX100）、阳离子型十六烷基三甲基溴化铵（CTAB）及生物表面活性剂鼠李糖脂和脂肽,研究表面活性剂对三氯乙烯的增溶能力.结果表明,5种表面活性剂浓度在临界胶束浓度（CMC）以上时,TCE在水相中的表观溶解度随表面活性剂浓度的增大而线性增大.质量增溶比（WSR）和摩尔增溶比（MSR）为鼠李糖脂〉脂肽〉CTAB〉TX100〉SDS.在各表面活性剂溶液中,所用的各表面活性剂质量浓度顺序为SDS#TX100=CTAB#鼠李糖脂=脂肽,两种生物表面活性剂的质量浓度仅为SDS的1%,但生物表面活性剂对TCE的饱和增溶容量有更好的提高效果.因此,相比之下,生物表面活性剂对TCE的增溶能力较强,其中以鼠李糖脂为最佳,而在化学合成表面活性剂中阳离子表面活性剂CTAB增溶TCE的效果最优.
英文摘要：
Solubilization of trichloroethylene（TCE） by different types of surfactants was investigated.Anionic surfactant SDS,nonionic surfactant Triton-100（TX100）,cationic surfactant CTAB and biosurfactants rhamnolipids and lippeptides were selected for the study of TCE solubilization.The results showed that the solubilities of TCE increased with the surfactant concentration above its CMC.The weight solubilization ratio（WSR） and molar solubilization ratio（MSR） were in the order of rhamnolipids lippeptides CTAB TX100 SDS.In the solution of five surfactants,although the mass concentration of each surfactant used was in the order of SDS #TX100 = CTAB #rhamnolipids = lipid peptides,the mass concentration of two biosurfactants was only 1% of SDS.Biosurfactants had better effect on TCE saturated solubilisation capacity,and the rhamnolipids are the best.Among chemical synthesis surfactants,cationic surfactant CTAB has optimal effect on solubilization of TCE.
