【摘要】：溶解态黑碳是黑碳连续体中可溶解于水的组分,是连接陆地土壤和海洋底泥两个主要黑碳库的关键纽带。溶解态黑碳也是天然可溶性有机质的重要组分,富含芳香微域结构和羧基、羟基、羰基等功能性官能团,具有较高的反应活性,可介导污染物在环境中的分配和转化过程。因此,研究溶解态黑碳的环境地球化学行为对研究全球碳循环以及污染物的环境归趋和效应都具有重要意义,已成为了相关领域的前沿和热点。本文综述了十余年以来溶解态黑碳在环境过程方面的研究进展,重点阐述了溶解态黑碳的定性、定量分析方法,在环境中的含量和空间分布、结构特征、环境转化过程,以及其对污染物吸附、氧化还原转化、光转化等环境行为的影响,并在此基础上对溶解态黑碳的未来研究方向进行了展望。
[Abstract]:Soluble black carbon is a water-soluble component of black carbon continuum and a key link between two major black carbon pools, terrestrial soil and marine sediment. Soluble black carbon is also an important component of natural soluble organic matter, rich in aromatic microdomain structure and carboxyl, hydroxyl, carbonyl functional groups, with high reactivity, and can be mediated. Therefore, it is of great significance to study the environmental geochemical behavior of dissolved black carbon for studying the global carbon cycle and the environmental fate and effect of pollutants. This paper reviews the environmental processes of dissolved black carbon in the past decade. In this paper, the qualitative and quantitative analysis methods of dissolved black carbon, the content and spatial distribution of dissolved black carbon in the environment, the structural characteristics, the process of environmental transformation, and the effects of dissolved black carbon on environmental behaviors such as pollutant adsorption, oxidation-reduction conversion, and photoconversion are discussed.
