Abstract The characteristics of dissolved organic matter(DOM) and three-dimensional fluorescence spectroscopy(3D-EEMs) of each component of source water in South-China reservoir were analyzed by fluorescence regional integration(FRI) and Supelite DAX-8 Macroporous Resin. the relationship between disinfection by-products formation potential, water quality indicators and fluorescence intensity were also determinated. The proportion of hydrophobic substances in the reservoir was more than 70% of UV₂₅₄. The fraction of HOB(hydrophobic bases) mainly contained tyrosine-like proteins and tryptophan-like proteins, while the fraction of HOA(hydrophobic acids) and HIS(hydrophilic substances) contained more fulvic acid. The trihalomethane formation potentials (THMsFP) of HOA, HOB, HON and HIS fractions were 151.5~194.1μg/L, 60.6~65μg/L, 123.4~189.9μg/L and 104.1~187.1μg/L, respectively, and the haloacetamide formation potential(HAcAmsFP) were 2.7~3.7μg/L, nd~0.1μg/L, 1.3~3.9μg/L and 2.2~8.4μg/L, respectively. The precursors of THMs(trihalomethane) and HAcAms(haloacetamide) were distributed uniformly in HOA, HON and HIS fractions. UV₂₅₄(R²=0.93), HIX(R²=0.59) presented a good linear relationship with THMsFP, which can be used as an indicator for predicting THMsFP among fractions. UV₂₆₀(R²=0.80) and DON(R²=0.74) showed a relatively good linear relationship with HAcAmsFP, which can be used as the parameters for predicting HAcAmsFP. Pearson correlation analysis manifested that the two humus-like regions(III,V) were significantly correlated with the formation potential of THMs, which meant that these substances were important precursors of THMs of source water in the reservoir. The formation potential of THMs and HAcAms can be predicted by the fluorescence regional integration among the fractions.
