Polycyclic Aromatic

Laser-induced solid-surface room-temperature phosphorimetry (SSRTP) has been employed for the detection of polycyclic aromatic hydrocarbons. A nitrogen-pumped laser and a dye laser were used as excitation sources. The effects of sample volume, laser irradiation, and background reduction treatment on the precision and sensitivity of the method were studied. With the use of thallium(I) acetate as a phosphorescence enhancer, picogram limits of detection were estimated for phenanthrene, pyrene, benzo[ g,h,i]perylene, chrysene, coronene, and 1,2-benzofluorene. The study demonstrates that laser excitation can improve the sensitivity of SSRTP by up to three orders of magnitude.

Effect Of Light

Polycyclic aromatic hydrocarbons (PAHs) are a class of genotoxic environmentalcontaminants and are always exposed to solar radiations. Fluorenes are important PAHswidely distributed in nature and hence the studies in the effect of light on them are of ulmostsignificance. Therefore in this paper, we have studied the photo irradiations of fluorene (1)and 9-fluorenone (2) with UV light in different solvents, which results in the formation ofdifferent products.
