Voltammetric determination of caffeine in beverages using a chemically modified electrode.

Abstract

A Nafion-ruthenium oxide pyrochlore chemically modified electrode is used for the determination of caffeine in beverages by square-wave voltammetry. Compared to a bare glassy carbon electrode, the chemically modified electrode exhibits a marked enhancement of the current response. A linear calibration curve is obtained over the 5-200 microns range in 0.05 M… (More)
