Potentiometric behavior of graphite-epoxy electrochemical transducers towards anions, cations and pH in aqueous media

In the present work, a study of the effect of anions, cations and pH in the potentiometric response of a graphite–epoxy composite is reported. The results obtained indicate a better response for anionic than for cationic ions, with those of greater magnitude being towards OH– and H+ respectively. It...

Sumario:In the present work, a study of the effect of anions, cations and pH in the potentiometric response of a graphite–epoxy composite is reported. The results obtained indicate a better response for anionic than for cationic ions, with those of greater magnitude being towards OH– and H+ respectively. It is possible to give an explication that is in agreement with the results obtained, for some behaviors in the response of chemical sensors and biosensors based on the study of this transducer; likewise some interesting direct and practical applications, are suggested and explored.
