title: [Constant-energy synchronous fluorescence spectrometry for simultaneous determination of anthracene and 9,10-dimethylanthracene].
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 microg x mL(-1) and 0-5 microg x mL(-1) respectively. The detection limits of anthracene and 9,10-dimethylanthracene were 2.2 ng x mL(-1) and 1.7 ng x 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.
