Abstract:

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.

Key words: polyaspartic acid (PASP), iminodisuccinate acid (IDHA), treatment of soil heavy metal, chemical method, biological method
