| 环境中溶解有机质与重金属的反应影响重金属的化学行为。近十几年来,研究者通过将平行因子分析和二维相关技术与传统光谱法相结合,对不同环境中溶解有机质与重金属的反应过程进行了深入研究,特别是研究了有机质中不同化学组分或官能团与重金属的络合顺序。本文根据近十四年发表的与溶解有机质-重金属反应相关的论文,按照溶解有机质来源分类,总结了不同溶解有机质的化学组成及其与重金属的络合过程。溶解有机质来源对其组成和结构有重要影响,溶解有机质中不同组分和官能团与重金属的络合顺序主要受重金属种类和溶解有机质组成结构的影响。溶解有机质中的酚基、羧基、酰胺和多糖基团是其与重金属反应的主要官能团。未来对溶解有机质与重金属反应过程的研究应更多关注多元络合物对反应过程的影响以及大气环境溶解有机质与重金属的反应过程。 |
| 英文摘要: |
| Dissolved organic matter affects chemical behavior of heavy metals in the environment through chemical reactions. In the past two decades, by combining the parallel factor analysis and two-dimensional correlation technology with traditional spectroscopy technique, deeper understandings of the reactions between dissolved organic matter and heavy metals in different environments, especially complexation between different chemical components or functional groups of dissolved organic matter and heavy metals have been realized. In this paper, research progress about the chemical composition of dissolved organic matter and the reactions between dissolved organic matter and heavy metals in different environments within the past fourteen years are summarized, and the results are classified according to the sources of dissolved organic matter. The composition and structure of dissolved organic matter are mainly affected by the source of dissolved organic matter, and the complexation order between different components or functional groups and heavy metals is mainly affected by heavy metals and the composition of dissolved organic matter. In addition, phenolic, carboxyl, amides and polysaccharide in dissolved organic matter are the main functional groups in dissolved organic matters binding heavy metals. In the future, researches about the influence of multicomponent complexes on the reaction process between heavy metal and dissolved organic matter and reaction process between heavy metal and dissolved organic matter in atmospheric environment should be considered. |
