Abstract :
Copper (Cu(II)) is an essential and necessary micronutrient for many plants and animals at very low levels. However, it is toxic to aquatic plants at high levels due to its association with cell membranes. Glassy carbon electrode (GCE) was modified by the 3-phenyl-4-[2-(2-naphthylsulfonyloxy)-benzylidenamino]-4,5-dihydro-1H-1,2,4-triazol-5-one (3-PNO) in 0.1 M supporting electrolyte. The modified surface was confirmed by cyclic voltammetry (CV) and x-ray photoelectron spectroscopy (XPS). According to characterization data, the GCE with 3-PNO was successfully obtained. The GCE with 3-PNO was utilized for Cu(II) ions analysis in water samples. The concentration range and the limit of detection (LOD) were 1.0×10-10 - 2.0×10-8 M and 2.0×10-11 M (S/N=3), respectively.
