Abstract

Bakır
(Cu (II)) çok düşük seviyelerde birçok bitki ve hayvan için gerekli ve gerekli
bir mikro besleyicidir. Bununla birlikte, hücre zarları ile birleşmesi
nedeniyle su bitkileri için yüksek seviyelerde toksiktir. Camsı karbon elektrot
(GCE),  3-fenil-4-[2-(2-naftilsülfoniloksi)-benzilamino]-4,5-dihidro-1H-1,2,4-triazol-5-on
(3-PNO) ile 0,1 M destek elektrot içinde modifiye edildi. Modifiye edilmiş
yüzey dönüşümlü voltametri (CV)  ve
X-ışınları fotoelektron spektroskopisi ile karakterize edildi. Karakterizasyon
sonuçlarına göre modifiye elektrot başarılı bir şekilde elde edildi. 3-PNO ile
modifye edilmiş GCE, Cu(II) iyonunun su numunesinin içinde analizi için
kullanıldı. Konsantrasyon aralığı ve deteksiyon limiti sırasıyla 1.0×10-10 -
2.0×10-8 M ve 2.0×10-11 M (S/N = 3), olarak bulundu.

A novel Cu(II) detection assay via modified glassy carbon electrode

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.
