Utilizing of 2-Amino-3-hydroxypyridine Modified Glassy Carbon Electrode to Detect Copper(II) Ions

Abstract

In this paper, 2-amino-3-hydroxypyridine modified glassy carbon electrode was used for the electrochemical analysis of trace copper(II) ions by square wave voltammetry technique. The modification of the glassy carbon electrode by 2-amino-3-hydroxypyridine solution was performed in the potential range between -150 mV and +600 mV by 30 cycles at 100 mV s -1 potential scan rate in non-aqueous media by cyclic voltammetry. The surface characterizations of this sensor electrode were performed by cyclic voltammetry. A lower detection limit would be reached in the presence of Britton-Robinson buffer solution at pH 5 for determination of Cu(II) ions by square wave voltammetry. The voltammetric response of the electrode was linear within the Cu(II) ion concentration range from 1.0 ×10 -12 M to 1.0 × 10 -6 M and the detection limit of 1.0 × 10 -12 M. The modified electrode offered an excellent way, with a high stability, simple, rapid, low cost and reusability, for selective determination of Cu(II) ions in Acigöl lake (in Afyonkarahisar, Turkey) water sample.
