چکیده انگلیسی
This paper presents the phosphorescence characterization of polycyclic aromatic hydrocarbons (PAHs) on solid-surface for obtaining new flow-through phosphorescence optosensors for PAHs-based on-line, immobilized onto a non-ionic resin solid support coupled to a continuous flow system and the applications for the selective determination of benzo(a)pyrene (BaP). The phosphorescent characterization of 15 PAHs, described as major pollutants by the Environmental Protection Agency (EPA) (naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, chrysene, benzo(a)anthracene, benzo(k)fluoranthene, benzo(b)fluoranthene, benzo(a)pyrene, indeno(1,2,3-cd)pyrene, benzo(g,h,i)perylene and dibenzo(a,h)anthracene) has been carried out. The experimental variables (heavy atom, deoxygenation and organic solvent in samples) for obtaining different possibilities for developing mono and multi-parameter PAH sensors and the conditions for PAH screening have been carefully studied and the experimental conditions to determination of BaP in presence of other PAHs in water samples have been optimized.
