摘要
聚天冬氨酸是一类可生物降解的环境友好型绿色阻垢剂。为了提高聚天冬氨酸的阻垢缓蚀性能,目前对聚天冬氨酸的改性主要有引入羟基、磺酸基、羧酸基以及与谷氨酸共聚等方法。不同改性方法获得的聚天冬氨酸具有不同的生物降解性能,并通过改变结垢晶体的形貌和尺寸而表现出不同的阻垢缓蚀性能。因此,后续研究工作应从阻垢机理方面入手,为特定水样定制最佳的改性方法。
The biodegradable polyaspartic acid （PASP） is a type of environmentally friendly scale inhibitor for water treatment. In order to improve the scale and corrosion inhibition effect of PASP, some modification methods such as introducing hydroxyl group, sulfonyl group, carboxyl group, and copolymerization with glutamic acid were reported. The biodegradability of PASP and the morphology and size of scale crystal are affected by the modification methods, which lead to different scale and corrosion inhibition ability. Therefore, special modification method should be developed for a particular water sample based on the mechnism of scale inhibition.
