天然锰氧化合物具有较大的比表面积和相对较高的氧化还原电位。同时在各种自然环境介质中都发现有天然锰氧化合物的存在。天然自然环境中不少有机物的迁移转化过程显然是涉及到了天然锰氧化合物的参与。因此,对自然环境中有机物迁移转化过程中天然锰氧化合物的参与作用的研究对评估有机污染物环境风险和探索有机污染的生成机理都有不小的参考价值。本文对天然锰氧化合物的种类、分布、理化性质以及目前对其参与的一些典型有机污染物迁移转化过程的研究做了简要介绍。
Natural manganese oxide compounds have a large specific surface area and a relatively high redox potential. At the same time in a variety of natural media found in the presence of natural manganese oxide compounds. Natural organic matter in many natural migration and transformation process is obviously related to the natural manganese oxygen compounds involved. Therefore, the study of the natural manganese oxide compounds involved in the migration and transformation of organic matter in the natural environment is of great reference value for assessing the environmental risk of organic pollutants and exploring the formation mechanism of organic pollutants. In this paper, the species, distribution, physico-chemical properties of natural manganese oxides and their current research on the migration and conversion of some typical organic pollutants are briefly introduced.
