Simultaneous determination of 1-chloroanthracene and 9-bromoanthracene by using matrix isopotential synchronous fluorescence spectrometry combined with derivative technique

Matrix isopotential synchronous fluorescence spectrometric (MISF) method combined with derivative technique has been proposed to determine two spectrally-badly-overlapped anthracene derivatives, 1-chloroanthracene and 9-bromoanthracene, simultaneously. An optimal scanning route of MISF spectra was chosen. By using the novel method, 1-chloroanthracene and 9-bromoanthracene have been determined directly and simultaneously without tedious pre-separation in its mixture. The recoveries of 1-chloroanthracene and 9-bromoanthracene for the analysis are 83.5% ≃ 94% and 90.0% ≃ 94.0% respectively and their limits of detection are 0.69μg/L and 10μg/L respectively.
