Advances in Methods and Applications for Characterizing the Chemi-cal Composition of Dissolved Organic Matter
摘要
Abstract
Dissolved organic matter(DOM)is widely distributed in various ecosystems,such as wa-ter,glacier,sediment,and soil.As a key component of the global carbon cycle,DOM plays a cru-cial role in the regulating aquatic ecosystem dynamics and influencing global climate change.Com-posed of a highly heterogeneous mixture of organic compounds that contain diverse functional groups,DOM presents significant challenges for accurate characterization.This paper reviews the applica-tions of several analytical techniques in resolving the chemical composition of DOM,including excita-tion-emission matrices(EEM),nuclear magnetic resonance spectroscopy(NMR),high-resolution mass spectrometry(HRMS),gas chromatography-mass spectrometry(GC-MS),and atomic force microscopy(AFM).The advantages and limitations of each technique are critically assessed,there-by highlighting their respective contributions to a comprehensive understanding of DOM.These re-sults provide insights into the chemical composition and structure of DOM,spanning from macroscop-ic to microscopic perspectives.However,the understanding of the composition and structure of DOM still needs to be further enhanced.Future research should aim to improve analytical techniques,in-cluding the development of new sample pretreatment and derivatization methods to reduce matrix in-terference,and the application of machine learning and artificial intelligence algorithms to enhance the ability to extract information from complex data.关键词
