“…2 shows that the five fluorescence region intensities were the most important indexes among others, while TOC, COD, and UV 254 made little contribution. This was mainly due to fluorescence data providing information on the composition and concentration of organics in the influent, which was inadequate for TOC, COD, and UV 254 [ 18 , 19 ]. Furthermore, the relative significance of the four parameters of catalyst formulation was more than 0.05, indicating that the effect on the output variable was not negligible.…”

“…Fluorescence spectroscopy, in which light is absorbed and the energy is re-emitted as fluorescence, can be applied to determine wastewater quality due to its fingerprint characteristics. Fluorescence data can quantify dissolved organic matter (DOM) [ 16 , 17 ], and provide information on the composition and concentration of DOM removed and transformed by wastewater treatment, in which traditional water quality parameters are inadequate [ 18 , 19 ]. Fluorescence spectroscopy has the advantages of fast measurement, high sensitivity and selectivity, and limited requirements for sample pretreatment [ 18 , 20 ].…”

Despite the advancements in analytical techniques, there are still great challenges and difficulties in accurately and effectively quantifying and characterizing dissolved organic carbon (DOC) in environmental samples. The objectives of this review paper are (a) to understand the roles and variability of DOC along the water continuum; (b) to identify the constraints, inconsistences, limitations, and artifacts in DOC characterization; and (c) to provide recommendations and remarks to improve the analytical accuracy. For the first objective, we summarize the four ecological and engineering roles of DOC along the water continuum from source water to municipal utility, including nutrients and energy sources, controlling the fates of micropollutants, buffering capacity, and treatability and precursors of disinfection byproducts. We also discuss three major challenges in DOC analysis, including spatial and temporal variations, degradability and stability, and unknown structures and formulas. For the second objective, we review the procedures and steps in DOC analysis, including sampling in diverse environmental matrices, isolation of DOC fraction, storage and preservation techniques, and analyses on bulk chemical characteristics. We list and discuss the available options and evaluate the advantages and disadvantages of each choice. Last, we provide recommendations and remarks for each stage: sampling, isolation, storage, and analysis.
