Electrocatalytic and Simultaneous Determination of Ascorbic Acid, Nicotinamide Adenine Dinucleotide and Folic Acid at Ruthenium(II) Complex‐ZnO/CNTs Nanocomposite Modified Carbon Paste Electrode

Abstract

The peak potentials recorded were 170, 500 and 830 mV vs. Ag/AgCl/KCl sat 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 3.0-700 mmol L À1 , with detection limits of 0.005, 0.5, and 1.0 mmol L À1 , respectively.

Evaluation of ZnO nanoparticle ionic liquid composite as a voltammetric sensing of isoprenaline in the presence of aspirin for liquid phase determination

“…Therefore, in continuation of our studies concerning the preparation of chemically modified electrodes for drug analysis [39][40][41][42][43], we describe the preparation of a new electrode composed of ZnO/NP ionic liquid (n-hexyl-3-methylimidazolium hexafluoro phosphate) paste electrode (ZnO/NP/IL/CPE) and investigate its performance for the voltammetric determination of ISN in aqueous solutions. We also evaluate the analytical performance of the modified electrode for simultaneous determination of ISN and ASP.…”
