摘要: Abstract DOM is often utilized as a control parameter in the design of water treatment process well others such efficiency and formation disinfection byproducts (DBPs), which removal characterization have received wide attention. Fluorescence excitation–emission matrix spectroscopy (EEMs) for flocculation at present not known. It this reason that EEMs study was employed to characterize Missouri River by process. The results showed four underlying components extracted from parallel factor (PARAFAC) were humic acid-like (A), fulvic (B), protein-like (C) unidentified component (D), while dominated A, B C. Flocculation effective hydrophobic organic compound A followed hydrophilic compounds C, whereas smallest molecular size C hard treat. Further illustrated pH 7, higher DOC THM efficiencies obtained, correlations with significant, thus indicating EEMs-PARAFAC offers robust analytical method assessing
