摘要

The aim of the present work remains in the improvement of amperometric ammonia analysis, using a polypyrrole film doped with DBSA anions. This large amphiphilic dopant promotes changes on the polymeric film presenting a more accentuated response and extending the linear response over a wide range of concentrations, when compare with films doped with small inorganic anions, such as chloride. The substituted pyrrole monomers, as N-methyl-pyrrole, was also used with the aim of investigating the role played by acid hydrogen present in polypyrrole. The response of the sensor was followed by EQCM and Raman Spectroscopy experiments as tools to elucidate the mechanism of ammonia detection.
