Description
This paper describes the development a novel ruthenium(II) complex-ZnO/CNTs modified carbon paste electrode (Ru(II)/ZnO/CNTs/CPE) for the electrocatalytic determination of ascorbic acid (AA). The objective of this novel electrode modification was to seek new electrochemical performances for the detection of AA, nicotinamide adenine dinucleotide (NADH) and folic acid (FA). The peak potentials recorded were 170, 500 and 830mV vs. Ag/AgCl/KClsat for AA, NADH and FA, respectively. The peak currents were linearly dependent on AA, NADH and FA concentrations using square wave voltammetry (SWV) method at the ranges of 0.008-251, 1.0-650, and 3.0-700μmolL-1, with detection limits of 0.005, 0.5, and 1.0μmolL-1, respectively. © 2014 WILEY-VCH Verlag GmbH & Co.
