摘要
聚天冬氨酸具有无毒、阻垢效率高、可生物降解等特点,是一种新型的绿色环保型水处理剂。本文在简要回顾阻垢剂合成的基础上,综述了近几年在聚天冬氨酸高分子结构改性方面的研究进展,其改性主要是通过在聚天冬氨酸分子结构上引入一些具有阻垢性能的官能团,如羟基、磺酸基和磷酸基等,改性后的聚天冬氨酸具有更好的性能。最后也对其发展方向进行了分析和展望。
Polyaspartic acid has the characteristics of high efficiency of scale inhibition,non- toxic,biodegradable as a new type of green and environmental water treatment agent. The synthesis method of polyaspartic acid was briefly demonstrated. At the same time,efforts done in recent years were summarized in terms of its modification to get better performance. The modification was mainly through the introduction of some of functional group of scaling inhibition performance in the molecular structure of polyaspartic acid,such as hydroxyl,sulfonic acid and phosphoric acid radical.The developing trends of the modified PASP were also analyzed.
