摘要
本研究综述了土壤重金属污染的研究进展,对天冬氨酸的2种绿色衍生物聚天冬氨酸(PASP)和亚氨基二琥珀酸(IDHA)进行了相关介绍,并针对其作用特点总结了2种物质在土壤重金属污染治理方面的相关研究和应用进展。最后,笔者提出了在土壤重金属污染治理方面这2种化合物的应用前景和使用方向,认为这2种化合物可以将化学法与生物法结合起来进行土壤重金属污染的治理,能有效提高重金属治理的速率,应用前景广阔。
This study reviewed the research progress of soil heavy metal pollution,introduced two biological derivatives of L-Aspartic acid,polyaspartic acid(PASP)and iminodisuccinate acid(IDHA),and summarized the research on the two compounds and their application in the treatment of soil heavy metal pollution.At the end of the paper,the author put forward the application direction and prospect of these two compounds in the treatment of soil heavy metal pollution,pointed out that these two compounds could be used to combine chemical and biological methods for the treatment of soil heavy metal pollution,effectively increase the rate of heavy metal treatment and have a broad application prospect.
