Characterization and Analysis of DOM in Raw Water in Xiamen and Zhangzhou by 3-DEEM-FRI
3-DEEM fluorescence spectroscopy and original fluorescence integration (3DEEM-FRI) analysis were adopted to analyze the correlation between the normalized fluorescent integral volumes and the fluorescence characteristics of the dissolved organic matter (DOM) in the raw water from reservoirs in Xiamen and Zhangzhou. The results showed that the components of aromatic protein (Component Ⅰ, C1 and Component Ⅱ, C2) and the fulvic acid (Component Ⅲ, C3) were significantly detected in all water samples. The component of soluble microbial metabolites (Component Ⅳ, C4) were detected in the water sample of Lianhua reservoir, Bantou reservoir and Shidou reservoir, while the component of humic acid (Component Ⅴ, C5) were not found obviously in any of the water samples. The relative contents of the same component are similar in different water samples. The proportion of aromatic protein components (P1, n+P2, n) is larger than 60%. The proportion of fulvic acid components (P3, n) is between 10% and 20%, as well as microbial metabolites components (P4, n), while the proportion of humic acid components (P5, n) is lower than 6%. The fluorescence characteristic parameters (1.28
