The front-face fluorescence spectrometry was developed for determination of migration amount of fluorescent whitening agents in washing products. The glass fiber paper was used as the adsorbent. The fluorescent whitening agents in washing products could be adsorbed onto the adsorbent. The adsorbent was directly measured with a self-assembly front-face fluorescence spectrometer. The linear range for the determination of fluorescent whitening agents was 10.0-500.0 μg/kg, and the limit of detection was 2.8 μg/kg. Ninety-six kinds of washing products were analyzed and the migration amounts of the whitening agents in 12 kinds of washing products were detectable. The correlation of analytical results of the 96 samples obtained by the present method with these obtained by the visual colorimestry was satisfactory. The present method was simple, rapid, and accurate and could be applied to the determination of the migration amount of the fluorescent whitening agents in the washing products.
