ANALYTICAL DETERMINATION OF POLYCYCLIC AROMATIC-HYDROCARBONS IN GASESFROM COAL CONVERSION BY SYNCHRONOUS FLUORESCENCE SPECTROMETRY

A method to analyze the most hazardous Polyclyclic Aromatic Hydrocarbo ns (PAH) (acenaphtene, anthracene, benzo(a) anthracene, benzo(a)pyrene , biphenyl, coronene, chrysene, dibenzo (a,h) anthracene, phenantrene, fluoranthene, fluorene, naphtalene and pyrene), by using excitation a nd energy constant synchronic fluorescence has been researched in dept h in this study. Spectral studies carried out allow characteristic pea ks to be obtained for the qualitative identification of 8 from 11 PAH tested. From the quantitative and interference studies, the most impor tant analytical characteristics (linear range, detection limit and rep roduciblity) for the determination of ten of these compounds have been obtained. The method was applied to the PAH determination in two diff erent samples: 1) air filter samples for urban pollution control and 2 ) air samples from a laboratory scale coal carbonization oven. Fluoren e (in the first type) and benzo (a) pyrene (in the second type), were identified and quantified.
