Analysis of the compositions, nature, and origins of the characteristic contaminants in wastewaters is important for water pollution control, treatment of pollution accidents, and the responsibility determination of environmental quality . Fluorescence spectroscopy can be used to analyze humic substances, amino acids, fluorescent whitening agents, lignin, polycyclic aromatic hydrocarbons and so on in wastewaters based on the characteristic fluorescence spectra of these substances. This paper first introduces the principle of fluorescence spectroscopy . Then it summarizes the applications of three-dimensional fluorescence spectroscopy and synchronous fluorescence spectroscopy in the study of characteristic dissolved or ganic matters in wastew aters. It also discusses the impacts of environmental factors on fluorescence spectroscopy. Finally, it provides an outlook of the future development of this technology with a view to providing a reliable analytical approach for characteristic dissolved organic matters in wastewaters.
