Dissolved organic matter (DOM) plays a critical role in determining the quality of wastewater and the safety of drinking water. This is the first review to compare two types of popular DOM monitoring techniques, including absorption spectroscopy and fluorescence excitation-emission matrices (EEMs) coupled with parallel factor analysis (PARAFAC) vs. Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS), for the applications in wastewater and drinking water treatments. The optical techniques provide a series of indices for tracking the quantity and quality of chromophoric and fluorescent DOM, while FT-ICR-MS is capable of identifying thousands of DOM compounds in wastewater and drinking water at the molecule level. Both types of monitoring techniques are increasingly used in studying DOM in wastewater and drinking water treatments. They provide valuable insights into the variability of DOM composition in wastewater and drinking water. The complexity and diversity of DOM highlight the challenges for effective water treatments. Different effects of various treatment processes on DOM are also assessed, which indicates that the information on DOM composition and its removal is key to optimize the treatment processes. Considering notable progress in advanced treatment processes and novel materials for removing DOM, it is important to continuously utilize these powerful monitoring tools for assessing the responses of different DOM constituents to a series of treatment processes, which can achieve an effective removal of DOM and the quality of treated water.
溶解有机质（DOM）在决定废水质量和饮用水安全方面起着至关重要的作用。这是第一篇综述，比较了两种流行的 DOM 监测技术，包括吸收光谱法和荧光激发-发射矩阵（EEMs）与平行因子分析（PARAFAC）与傅里叶变换离子回旋共振质谱（FT-ICR-MS），用于废水和饮用水处理。光学技术提供了一系列指标来跟踪发色和荧光 DOM 的数量和质量，而 FT-ICR-MS 能够在废水和饮用水中以分子水平鉴定数千种 DOM 化合物。这两种监测技术在研究废水和饮用水中的 DOM 方面的应用越来越多。它们为研究废水和饮用水中 DOM 的组成变化提供了有价值的见解。DOM 的复杂性和多样性突出了有效水处理的挑战。还评估了各种处理过程对 DOM 的不同影响，这表明 DOM 组成及其去除的信息是优化处理过程的关键。考虑到先进处理过程和新型去除 DOM 材料的显著进展，利用这些强大的监测工具来评估不同 DOM 成分对一系列处理过程的响应非常重要，这可以实现有效去除 DOM 和处理水的质量。
