Simultaneous determination of dissolved anthracene and pyrene in aqueous solution by synchronous fluorimetry

A synchronous fluorimetry for simultaneous determination of dissolved anthracene and pyrene in aqueous solution has been established. The linear ranges for determination of dissolved anthracene and pyrene were 1.00 × 10−8 to 4.50 × 10−7 mol L−1 and 5.00 × 10−9 to 6.50 × 10−7 mol L−1, and the limits of detection (LOD) for anthracene and pyrene were 2.23 × 10−9 and 8.24 × 10−10 mol L−1 with relative standard deviations (R.S.D.) of 2.90 and 2.34% (n = 5), respectively. Satisfactory results were obtained when the established method was used to simultaneously determine anthracene and pyrene in spiked water samples.
