| 摘 要： | 溶解性有机质(DissolvedOrganicMatter,DOM)在水生生态环境中广泛存在,影响着水环境中多种物质的生物地球化学性质。分析其组成与含量具有重要的生态环境意义,是生态环境科学领域研究的热点。溶解性有机质组成非常复杂,其分子组成的解析一直是难题。近年来,具有高分辨率、高灵敏度、高通量、高扫描速率等特性的静电场轨道阱质谱技术,结合计算机编程技术、可视化技术对DOM分子组成分布特征进行表征,可大幅提升对DOM的解析能力。本文总结了DOM的高分辨质谱数据表达方法,综述了静电场轨道阱质谱技术的发展及其表征水体中DOM的应用现状,并对未来研究进行展望。

| Abstract: | Dissolved organic matter (DOM) exists widely in the aquatic ecological environment and has a significant influence on the biogeochemical properties of many substances. Its composition and content have important ecological and environmental significance and has been a hot spot in ecological and environmental science research. The composition of DOM is complex, and its molecular composition analysis has always been a challenge. In recent years, Orbitrap mass spectrometry (Orbitrap MS), capable of high resolution, high sensitivity, high throughput, and high scanning rate, combined with computer programming technology and visualization technology could be used to characterize the molecular composition and distribution of DOM, greatly improving the capabilities of DOM. In this paper, the explanation methods of DOM high-resolution MS data are summarized, the Orbitrap MS technology and its application status in characterization of DOM in water are reviewed, and the prospects for future developments are analyzed. |
