Özet
Conducting poly(2-aminothiazole) (PAT) film was electrodeposited on platinum disc electrode surface by cyclic voltammetry of 2-aminothiazole (AT) for stripping voltammetric determination of Hg(II). Hg(II) was pre-concentrated on to polymer matrix by adsorption upon dipping the modified electrode into Hg(II) solution. The effect of electrolysis time, number of electropolymerization cycles, pH, preconcentration time and Hg(II) concentration on the determination of Hg(II) were studied. A linear relation between the peak current and Hg(II) concentration was obtained in the range of 0.1-1.1 mg L-1. The relative standard deviation was calculated as 1.37% at 0.5 mg L-1 Hg(II) (n=6). The detection limit was estimated as 0.025 mg L-1 by means of 3:1 current-to-noise ratio. The interferences of Ni(II), Cu(II), Pb(II), Zn(II), Cd(II) and Fe(III) were investigated in the determination of Hg(II). The optimized method was successfully applied to the determination of Hg(II) in the River Kizilirmak samples by means of standard addition method.
