Investigation on simultaneous analysis of multicomponent polycyclic aromatic hydrocarbon mixtures in water samples: a simple synchronous fluorimetric method

Simultaneous analysis of multicomponent polycyclic aromatic hydrocarbons in mixture of micellar solution (CTAB) has been investigated. A simple synchronous fluorimetric method has been used, which does not require pretreatment of data, solving of large amount of data and large amount of solution preparation for internal calibration, thus making the analysis simple and fast. The method is fairly successful for analysis of 6, 7 and 10 components in a mixture solution. Attempt for 18-component analysis, however, shows a poor recovery for PAHs with low fluorescence. The detection limits are generally between 0.055 and 12.97 ng ml(-1) except for benzo[b]anthraccene with detection limit of 32.21 ng ml(-1). (C) 2001 Elsevier Science B.V. All rights reserved.
