海泡石是一种吸附性很强的黏土矿物, 在修复土壤、水体重金属污染中具有很强的优越性。本文介绍了海泡石修复机理及其改性方法, 并综述性介绍了海泡石在降低农产品重金属(镉、汞、砷、铅、锌和铬等)含量和净化水体重金属污染方面的研究进展。与天然海泡石相比, 改性海泡石及其复配具有针对性强、修复效果好和修复范围广等优点。

Sepiolite is a kind of clay mineral with strong adsorbability, which has strong superiority in re-pairing heavy metal pollution in soil and water. Herein, the repair mechanism and modification methods of se-piolite are introduced, and the research progress of sepiolite in reducing the content of heavy metals (cadmium, mercury, arsenic, lead, zinc and chromium, etc.) in agricultural products and purifying water heavy metal pol-lution is reviewed. Compared with natural sepiolite, modified sepiolite and its combination products have po-tential advantages of strong pertinence, good repair effect and wide repair range.
