【摘要】 为深入揭示水溶性有机物(DOM)对土壤中重金属迁移性影响形成机制的研究现状及发展趋势,通过对国外相关文献的分析与比较,阐述了DOM通过吸附-解吸作用、络合作用及溶解-沉淀作用等化学行为实现对重金属迁移性影响的作用特点与规律,并指出了值得近一步深入的研究问题,为今后相关研究的深入及成果的应用提供有益的借鉴作用。更多还原

【Abstract】 Dissolved organic matter (DOM) has significant influence on the chemical actions of heavy metal in soil, through adsorption-desorption, complex and dissolution-deposition, and results in changing the concentration of heavy metal ions and its mobility. The researchs on the mechnism of effect of DOM on the mobility of heavy metals in soil environment are reviewed, and several available projects are suggested to be further studied to expolite the mechnism and its application.更多还原
