Clay minerals are ubiquitous in soil and sediments, and play important roles in environmental processes. Virtually all clay minerals contain some Fe, either in the crystal structure or adsorbed at the surface of the clay minerals, which could promote many reactions on the clay minerals. The interaction between Fe containing clay mineral and its surrounding contaminants would greatly affect the transformation and toxicity of the contaminants. While it is certain that the Fe plays important roles in the fate of the contaminants, relative qualitative and quantitative assessment of these processes is limited. Based on the overall toxicity variation, this paper reviews the active areas of the researches on the interactions between Fe containing clay mineral and contaminants, and provides perspectives for future work.
粘土矿物在土壤和沉积物中无处不在，在环境过程中起着重要作用。几乎所有的粘土矿物都含有一些铁，无论是在晶体结构中还是在粘土矿物的表面吸附，这都可以促进粘土矿物上的许多反应。含铁粘土矿物与其周围污染物之间的相互作用将极大地影响污染物的转化和毒性。虽然可以确定铁在污染物的归宿中起着重要作用，但对这些过程的相对定性和定量评估是有限的。基于整体毒性变化，本文综述了含铁粘土矿物与污染物相互作用的研究活跃领域，并为今后的工作提供了展望。
