Abstract
Aminylferrocene is successfully immobilized on nanosized gold colloid particles associated with a 1,4-benzenedimethanethiol monolayer on a gold electrode surface and characterized by cyclic voltammograms and electrochemical impedance spectroscopy. In a pH 7.0 phosphate buffer solution, the formal potential (E 0’) of Fc is 0.432 V (SCE), and the apparent surface electron-transfer rate constant is 0.89 s−. The immobilized Fc gives an excellent electrocatalytic response to the terbutaline oxidation. The catalytic-current response of differential pulse voltammograms increases linearly with the terbutaline concentration from 1.75 × 10−7 to 5.62 × 10−4 mol/l. The detection limit is 2.30 × 10−8 mol/l. The determination of terbutaline in a tablet dosage is satisfactory. The method is simple, quick, and sensitive.
