Dissolved organic matter (DOM) is a key component of aquatic ecosystems and the global carbon cycle. However, the lack of reference samples for endogenous freshwater DOM has hindered a deeper understanding of its environmental behavior and biogeochemical cycling. This study aims to provide a gram-scale, high-purity endogenous freshwater DOM reference sample. By employing an amplified solid-phase extraction method using modified styrene-divinylbenzene polymer resin-packed columns, 8tons of water from the central line project of South-to-North Water Diversion were processed, successfully yielding 13.12g of DOM, named as NSBD-DOM. A comprehensive suite of analytical techniques—including elemental analysis, Fourier transform infrared spectroscopy, excitation-emission matrix spectra, nuclear magnetic resonance spectroscopy, and high-resolution mass spectrometry—was employed to systematically compare NSBD-DOM with Suwannee River Fulvic Acid (SRFA) from the International Humic Substances Society. The NSBD-DOM was predominantly composed of fulvic acid like components, exhibiting characteristic of carbohydrate anomeric carbon, alkenes/conjugated alkenes, and amino sugars. Compared to SRFA, NSBD-DOM exhibited lower molecular weight, condensation degree, and oxygen content, accompanied by lower levels of polyphenols and polycyclic aromatics. However, it showed a higher H/C ratio and higher nitrogen content, with elevated levels of unsaturated aliphatic compounds and highly unsaturated compounds. NSBD-DOM exhibits typical endogenous characteristics, it can serve as a unified reference for studies on DOM's environmental behavior, carbon cycling, and related research fields.

溶解性有机质(DOM)是水生生态系统和全球碳循环的关键组分,但淡水内源DOM参考样品的缺乏,制约了对其环境行为和生物地球化学循环的深入理解.本研究旨在提供一种克级高纯度淡水内源DOM参考样品.通过放大的改性苯乙烯-二乙烯基苯聚合物树脂填充柱固相萃取法,处理南水北调中线工程8t河水,成功制备了13.12g DOM,命名为NSBD-DOM.综合运用元素分析、傅立叶变换红外光谱、三维荧光光谱、核磁共振波谱和高分辨质谱等手段,系统表征了NSBD-DOM的化学组成,并与国际腐殖酸协会提供的苏万尼河富里酸(SRFA)进行对比.结果表明,NSBD-DOM主体为类富里酸组分,包含碳水化合物端基碳、烯烃/共轭烯烃以及氨基糖等特征.相较于SRFA,NSBD-DOM的分子量、缩合度、氧元素含量较低,其中多酚类和多环芳烃类化合物含量较低;然而,其氢碳比、氮含量、不饱和脂肪族化合物和高度不饱和化合物含量较高.NSBD-DOM具备典型内源特征,可为DOM的环境行为、碳循环等研究提供参考.

溶解性有机质(DOM)是水生生态系统和全球碳循环的关键组分,但淡水内源DOM参考样品的缺乏,制约了对其环境行为和生物地球化学循环的深入理解.本研究旨在提供一种克级高纯度淡水内源DOM参考样品.通过放大的改性苯乙烯-二乙烯基苯聚合物树脂填充柱固相萃取法,处理南水北调中线工程8t河水,成功制备了13.12g DOM,命名为NSBD-DOM.综合运用元素分析、傅立叶变换红外光谱、三维荧光光谱、核磁共振波谱和高分辨质谱等手段,系统表征了NSBD-DOM的化学组成,并与国际腐殖酸协会提供的苏万尼河富里酸(SRFA)进行对比.结果表明,NSBD-DOM主体为类富里酸组分,包含碳水化合物端基碳、烯烃/共轭烯烃以及氨基糖等特征.相较于SRFA,NSBD-DOM的分子量、缩合度、氧元素含量较低,其中多酚类和多环芳烃类化合物含量较低;然而,其氢碳比、氮含量、不饱和脂肪族化合物和高度不饱和化合物含量较高.NSBD-DOM具备典型内源特征,可为DOM的环境行为、碳循环等研究提供参考.

Dissolved organic matter (DOM) is a key component of aquatic ecosystems and the global carbon cycle. However, the lack of reference samples for endogenous freshwater DOM has hindered a deeper understanding of its environmental behavior and biogeochemical cycling. This study aims to provide a gram-scale, high-purity endogenous freshwater DOM reference sample. By employing an amplified solid-phase extraction method using modified styrene-divinylbenzene polymer resin-packed columns, 8tons of water from the central line project of South-to-North Water Diversion were processed, successfully yielding 13.12g of DOM, named as NSBD-DOM. A comprehensive suite of analytical techniques—including elemental analysis, Fourier transform infrared spectroscopy, excitation-emission matrix spectra, nuclear magnetic resonance spectroscopy, and high-resolution mass spectrometry—was employed to systematically compare NSBD-DOM with Suwannee River Fulvic Acid (SRFA) from the International Humic Substances Society. The NSBD-DOM was predominantly composed of fulvic acid like components, exhibiting characteristic of carbohydrate anomeric carbon, alkenes/conjugated alkenes, and amino sugars. Compared to SRFA, NSBD-DOM exhibited lower molecular weight, condensation degree, and oxygen content, accompanied by lower levels of polyphenols and polycyclic aromatics. However, it showed a higher H/C ratio and higher nitrogen content, with elevated levels of unsaturated aliphatic compounds and highly unsaturated compounds. NSBD-DOM exhibits typical endogenous characteristics, it can serve as a unified reference for studies on DOM's environmental behavior, carbon cycling, and related research fields.
