Abstract
The development of sensors with rapidly, reliability and reproducibility for on-line monitoring environmental pollutants, have received great interest. In the present talk sensors fabricated by using conducting polymers such as polyaniline (PANI) and polypyrrole (PPy) as the active layers have been considered. The sensors based on conducting polymer film coating on the quartz crystal microbalance (QCM) electrode. The UV-visible spectroscopy was also used. Detection of a number of primary volatile organic compounds such as aliphatic alcohols, chlorinated hydrocarbons and amines vapours were discussed. Acid, pH, dye, silver, gold and iodine sensors are also considered.
