摘　　要：二聚表面活性剂是指通过联接基团把两个传统表面活性剂分子在其头基或接近头基的位置以化学键的方式联接在一起的一类特殊的表面活性剂。因其优异的溶液性能,二聚表面活性剂得到广泛应用。本文综述了二聚表面活性剂对重金属离子的去除作用,并阐述其去除机理和去除效果。与传统表面活性剂去除重金属离子的效果相比,二聚表面活性剂的去除金属离子效果更好,且联接基的性质对重金属离子的去除效果有重要影响。Dimeric surfactant are made up of two conventional amphiphilic moieties connected at the level of the head groups or very close to the head groups by a spacer group. The dimeric surfactant has been widely used because of its excellent solution properties. The removal of heavy metal ions by dimeric surfactants was reviewed, and its removal mechanism and the removal effect were reviewed in detail. Comparing the traditional surfactant, the removal effect of heavy metal ions of dimeric surfactant was better. Moreover, the properties of the spacer groups were very important influence on the removal of heavy metal ions.
