Recebido em 22/11/96; aceito em 21/5/97 POTENTIOMETRIC TRANSDUCERS BASED IN CONDUCTING POLYMERS: ANALYTICAL APPLICATIONS. A review is given about the most relevant advances on the analytical applications of conducting polymers in potentiometric sensors. These organic polymers represent a new class of materials with conducting properties due to its doping by ions. Several polymers already were synthesized such as polypyrrole, polyaniline, polythiophene, among others. Particular attention is

The correlation between structure, stability and ability to ion exchange of some conducting polymers applied as potentiometric transducers, is discussed.
