| dc.description.abstract | The objective of this work is to develop a system
of extraction of organic chemical compounds with toxic
properties, such as Polycyclic Aromatic Hydrocarbons
(PAHs) and Polychlorinated Biphenyls (PCBs), contam inants present in gaseous atmospheric samples (ambi ent air). The air samples are made up of a solid phase
mixture consisting of particulate matter (PM), and a gas eous phase. The devices for taking air samples collect
the samples on different types of filters, using poly urethane foam filters (PUF) to retain the gaseous phase,
which is extracted using organic solvents. The invention
is aimed to develop a mechanical and automatic method
to extract analytes from those filters, in order to increase
the extraction efficiency, and the reproducibility and re petitiveness of the analytical procedure; using a reduced
volume of solvents and shorter time of extraction (cost
reduction). | |
