摘要：

Three-dimensional(3D)excitation-emission matrix(EEM)fluorescence spectroscopy is applied to charac- terize the coal oil.The results show that the 3D fluorescence spectra of coal oil in aqueous solution mainly have one broad peak.This peak is identified at the excitation/emission wavelengths of 270/290 nm.The relation between the fluorescence intensity and the concentration of coal oil is also studied.When the concentration lies between 2-2000 ppm,the relation between the fluorescence intensity and the concen- tration of coal oil is well linear.The nature of solvents significantly affects the EEM fluorescence of coal oil.
