Abstract：A sort of analytical method of fast diagnosis of organic matter in water is discussed. The total luminescence spectra (TLS) of water samples in combination with laser induced fluorescence (LIF) measurements using 532 nm wavelength excitation source were measured in the laboratory. The spectra of dissolved organic matter (DOM) and chlorophyll a (Chl a) were pointed out and obtained with spectral fluorescence signature (SFS) technique. The spectrum of water Raman scattering and fluorescence of DOM and Chl a were separated from TLS with fiting Gaussian of the least squares method, and a high correlation coefficient excelling 0.996 4 was obtained. The results indicated the possibilities of water quality monitoring in real time and on line based upon SFS technique and fitting Gaussian of the least squares method.
