Application of clay minerals in remediation of heavy metal pollution in soil

In modern times where heavy metal pollution in soil is becoming more and more serious, the new natural non-polluting remediation methods represented by clay mineral materials have attracted more and more attention in the industry.In this paper, the research progress on the types and basic characteristics of clay mineral materials, the effect and mechanism of remediation of heavy metal pollution in soil at home and abroad was comprehensively discussed. The deficiencies of relevant studies were also summarized, and the future research trend was predicted.
