Modifiye edilmiş camsı karbon ile yeni bir Cu(II) analiz yöntemi

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

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.
