Eletrodos modificados com polímeros perfluorados e sulfonados: aplicações em análises ambientais

By Fungaro Denise Alves and Brett Christopher M. A.


Perfluoro and sulfonated ion-exchange polymers are recognized as a very useful material for various mechanistic studies and applications in electrochemistry. These polymers are characterized by high equivalent weights and by a low number of ion-exchange sites interposed between long organic chains. The solubility enables a preparation of stable polyelectrolyte films on the electrode surface. Examples of the determination of trace metals and organic componds in real environmental samples are presented
