| 摘 要： | 土壤中锰元素主要来自于成土母质,风化后的锰主要以锰氧化物形式存在于土壤中.锰氧化物因具有比表面积大、表面电荷低、对金属的亲合力强、氧化还原电位高等特性,对土壤中痕量金属的环境行为存在重要影响.化学提取方法是研究土壤中不同固相组分的重要手段.本文首先从土壤中锰的来源及主要存在形态出发,介绍了不同价态锰(+2、+3、+4)...

| Abstract: | Manganese(Mn)in soil mainly comes from parent minerals and weathered Mn mainly exists in soil in forms of Mn oxides.Manganese oxides have large specific surface area,low surface charge,strong affinity for metals,and high redox potential,hence they have important effects on environmental behavior of trace metals in soil.Chemical extraction is an important method to study the solid-phase components in soil.At first,this review introduced the source and existence of Mn oxides with different valences(+2,+3,+4)in soil,and the factors affecting the transformation of Mn;secondly,we summarized different types of Mn oxides in soil and their surface characteristics,adsorption abilities,redox properties;finally,the single extraction and the sequential extraction method of different forms of Mn in soil are summarized,as well as the application of the extraction method.This review provides a reference for the further study of Mn oxides in the soil. |
