ABSTRACT: The aim of this work was to study the electrochemical behavior of gold
electrode which was modified with p-tert-butylcalix[6]arene membrane and this
in the presence of different nickel ions based concentrations in order to form
a nickel electrochemical sensor. For that, impedance-spec- troscopy
characteristics have been investigated. The obtained results were then modeled
by appropriate equivalent circuit aiming at elucidating the electrical
properties of the modified gold transducer. A correlation between the present
impedimetric results and previous potentiometric ones was achieved traducing
then a fast ionic transfer.
