SIMULTANEOUS DETERMINATION OF FLUORENE, A CENAPHTHENE, ANTHRACENE ANDPERYLENE BY DERIVATIVE CONSTANT ENERGY SYNCHRONOUS FLUOROMETRY

The technique of derivative constant energy synchronous fluorimetry wa s introduced in this article. For mixture of fluorene, acenaphthene, a nthracene and perylene, the detection limit is 2.4, 17.1, 0.27, 0.043 ng/mL, respectively, when first-derivative constant energy synchronous fluorimetry is employed. The detection limit is 1.5, 15.0, 0.13, 0.02 2 ng/mL, respectively, when second-derivative constant energy synchron ous fluorimetry is employed. In the method, four compounds can be simu ltaneously determined without any mutual interference.
