Abstract: PAMAM dendrimer with special structure and properties is used in water treatment. It is efficient and innoxious as a water treatment agent. This paper summarizes the application research of PAMAM dendrimer on the removing of heavy metal ions，dye and silicon scale in water treatment. pH of solution，acting time，PAMAM dendrimer generation all have effects on treatment efficiency in the PAMAM dendrimer treatment of water. Besides，it can be regenerated when it is used to the removing of heavy metal ions. At last，this paper discusses the problems of PAMAM dendrimer in water treatment and predicts that the scope of application in water treatment could be further expanded by modifying PAMAM dendrimer or synthesizing new dendrimers in the future.

Key words: PAMAMdendrimer, water treatment, heavy metal ions, dyestuff, silicon scale

摘要： PAMAM树状大分子具有特殊结构与性能，应用于水处理中，具有无毒和高效的特点。本文综述了PAMAM树状大分子在含重金属离子废水、染料废水、高硅水等水处理中的应用研究。PAMAM树状大分子在水处理中的处理效果受溶液的pH值、作用时间、树状大分子的代数等因素的影响，且在含重金属离子废水处理中可再生。最后探讨了PAMAM树状大分子在水处理应用中存在的问题，预测未来将通过改性PAMAM树状大分子或合成新树状大分子扩大其在水处理中的应用范围。
