Özet
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 soution 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 solutin at pH 5 for determination of Cu(II) ions by square wave voltammetry. The voltammetric response of the electrode was linear within the Ci(II) ion concentration range from 1.0 x 10(-12) M to 1.0 x 10(-6) M and the detection limit of 1.0 x 10(-12) M. The modified electrode offered and excellent way, with a high stability, simple, rapid, low cost and reusability, for selective determination of Cu(II) ions in Acigol lake (in Afyonkarahisar, Turkey) water sample.
