δ-MnO2在环境中的演化及其与金属离子的相互作用研究进展
Evolution of δ-MnO2 in Environment and Its Interaction with Metal Ions:A Review
摘要
Abstract
As an important part of soil minerals and earth sediments,vernadite(δ-MnO2)have attracted much attention because of its super-strong enrichment of many metal ions in soil.δ-MnO2 enriched metal ions migrate and transform in soil environment,with the risk of secondary pollution of metal elements.Therefore,it is imperative to explore δ-MnO2 transformation process and their interaction with metal elements.This paper briefly introduces the properties of δ-MnO2,reviews the structural transformation of δ-MnO2 and their influential factors,the interaction of δ-MnO2 with heavy metal ions and the growth mechanism of manganese oxide crystals,and finally puts forward the research focus and direction of the prevention and control of secondary pollution of metal elements in soil caused by δ-MnO2 transformation process.关键词
