Abstract:

2-Aminothiazole was electropolymerized by cyclic voltammetry (CV) on the multi-walled carbon nanotubes (MWCNTs) modified glassy carbon electrode (GCE) surface. Poly(2-aminothiazole)/MWCNTs/GCE was used for determination of copper ions. The anodic peak currents of copper ions evaluated by differential pulse stripping voltammetry (DPSV) are linear with the concentrations in the range from 1.0 × 10−7 M to 2.0 × 10−5 M with a linear coefficiency of 0.9985. The detection limit is 2.0 × 10−9 M calculated for a signal-to-noise ratio of 3 (S/N =3). The proposed method was applied successfully to the determination of copper ions in drinking water, and the recovery was 96%.
