Study on the effect of modified porous materials on heavy metal remediation in agricultural fields

Abstract

With the rapid development of modern agriculture, the problem of heavy metal pollution and degradation of soil quality in agricultural soils has become increasingly serious, and the search for efficient, economical and environment-friendly heavy metal passivation materials has become a research hotspot for the solidification and stabilization of heavy metals in agricultural soils. In this paper, we summarize the remediation effect of porous materials on soil heavy metal pollution in view of existing studies, and analyze the changes of porous material properties and the influence on heavy metal remediation ability after modification and aging. Finally, the performance improvement of porous materials and their industrial application in the field of heavy metal pollution remediation are prospected.
