Abstract：A new method of constant-energy synchronous fluorimetry to determine anthracene and 9,10-dimethylanthracene simultaneously is suggested. The spectral resolution of the constant-energy synchronous fluorescence spectra of these two compounds was much higher than that of conventional spectra. The linear ranges for anthracene and 9,10-dimethylanthracene were 0-2 μg·mL-1 and 0-5 μg·mL-1 respectively. The detection limits of anthracene and 9,10-dimethylanthracene were 2.2 ng·mL-1 and 1.7 ng·mL-1 respectively，and the relative standard deviation was less than 2%. When the new method was used for the determination of anthracene and 9,10-dimethylanthracene in water samples, the recoveries were in the range of 85% to 103%. This method has proved to be simple and rapid.
