In this study, we have characterized three fluorescent components of dissolved organic matter (DOM) in the surface and underground water of one rare earth element ore district by excitation-emission matrix (EEM) fluorescence spectroscopy coupled with parallel factor analysis (PARAFAC). Two protein-like components (C1, tyrosine and C2, tryptophan) and one humic-like component (C3) were identified by the DOM Fluor-PARAFAC model, with C3 constituting more than 95% of the total DOM, while C1 and C2… CONTINUE READING
