摘要
表面活性剂因具有亲水亲脂的两亲性,已被广泛用来治理环境污染。介绍了表面活性剂在去除环境重金属中的应用,重点探讨了基于表面活性剂的液膜分离技术、胶团强化超滤技术、液泡吸收技术、改性吸附技术、异位淋洗技术、植物萃取技术等,并指出表面活性剂的应用前景是研究开发环境友好性的生物表面活性剂。
Surfactants were widely used to remediate contamination due to its amphiphilic structure as hydrophile and hydrophobe groups. The application of surfactants in removal of heavy metals from contaminated environment was introduced, with focus on discussion of surfactant-based techniques involving liquid membrane separation, micellar-enhanced ultrafiltration, metal-absorbing, modified-sorption, ex-situ soil flushing and enhanced phytoextraction. Environmental friendly biosurfactants is the frontier in this area.
