| 摘 要： | 本研究以离子液体1-甲基-3-丁基咪唑六氟磷酸盐(BM IM]PF6])作膜溶剂,利用支撑液膜分离技术,用0.1mol/L的氢氧化钠溶液作萃取溶液将三种环境内分泌干扰物壬基酚、辛基酚和双酚A进行分离。研究结果显示该支撑液膜分离技术对双酚A的萃取效果最好,其次是辛基酚,而壬基酚不被萃取。利用该技术能将三种混合物选择性地进行萃取分离,但萃取时间不宜超过46小时。

| Abstract: | In the study,ionic liquid 1-methyl-3-butylimidazolium hexafluorophosphate was first used as membrane solvent in supported liquid membrane extraction(SLME) to selectively extract the mixture of 4-nonylphenol(NP),4-tert-octylphenol(OP) and Bisphenol A(BPA) in water.The results indicated that BPA was successfully separated from the aqueous mixture of NP,OP and BPA by using 0.1mol/L of NaOH as the extraction solvent through SLME while just a little of OP was extracted and none of NP was extracted in the procedu... |
