Multivariate fluorimetric determination of mixture of pyrene, perylene andtriphenylene in water sample

Micellization is described as a successful media for simultaneous fluorimet ric determination of perylene, pyrene and triphenylene in water samples by reducing interference between them. A multivariate method based on synchron ous fluorescence scan to estimate perylene, pyrene and triphenylene in thei r mixture solution has been proposed. The method does not require solving o f large amounts of data obtained from the whole spectrum of the samples, th us making the analysis simple and fast. The method gives the best result fo r perylene and satisfactory results for pyrene and triphenylene. Analysis o f water samples of two differed origins spiked with known amount of perylen e, pyrene and triphenylene also gives satisfactory result. Presence of fluo ranthene up to 1 mu M does not interfere in the analysis.
