| Abstract: | Modelling for detecting dissolved organic matter with 32 water samples is addressed, using several typical organic characteristic peaks of 3D fluorescence spectra such as Peak A (humic-like), Peak C (humic-like), Peak B (tyrosine-like), Peak T1 (tryptophan-like) and Peak T2 (tryptophan-like). Experiments show that the modeling method is not satisfactory to detection of TOC and COD in water from different sources. It is concluded that the modeling method for detecting dissolved organic matters, based on the typical characteristic peaks of 3D fluorescence, is not universal for the variant water. |
