Application of the potentiometric and the amperometric methods for the redox potential determination
Résumé
Authors tried to explain the factors responsible for the high discrepancy obsd. between various potentiometric measurements in the literature. They performed a correlation between the potentiometric and the amperometric detn. of redox potentials, and then, detg. which of the two electrochem. techniques is the most appropriate according to the proper characteristics of a given sample. They also checked the behavior of the prepd. UMEs (suprasil, epoxy or polyester) in various concd. brines.
