摘要
比较了生物表面活性剂-皂角苷(Saponin)与两种化学表面活性剂-聚氧乙烯月桂醚(Brij35)和曲拉通100(TX100)对多环芳烃(PAHs)蒽在水溶液体系中的增溶作用,结果表明,在水溶液体系中,当表面活性剂的浓度在其临界胶束浓度(CMC)以下时,对蒽的增溶程度较弱,增溶顺序为:Saponin>Brij35>TX100;在CMC以上时,表面活性剂对蒽产生显著的增溶作用,增溶顺序为:Brij35>Saponin>TX100。因此,该增溶性研究可以为多环芳烃污染土壤的修复提供一定的理论依据。
The solubilizations of anthracene was characterized by using Saponin,and compared with two typical chemical surfactants(Brij35,TX100) in water solution.The results showed that the solubilization of anthracene was slightly enhance when dosages of surfactants were below their respective critical micelle concentration(CMC),and their solubilization capabilities were as follows Saponin>Brij35>TX100.However,the solubilization of anthracene was dramatically enhance when dosages of surfactants were over their respective CMC,and their solubilization capabilities were as follows Brij35>Saponin>TX100.As a result,the research provided some fundamental information for the remediation of PAH-contaminated soil.
