Kadmiyum (II) analizi için triazol türevi modifiye edilmiş camsı karbon

Öz

Camsı karbon elektrot (GCE), 3-Methyl-4-(4-hydroxybenzylidenamino)-4,5-dihydro-1H-1,2,4-triazol-5-one (MDT)’ nin fenol oksidasyonu ile 0.1 M destek elektrolit içinde modifiye olmuştur. Modifiye edilmiş yüzey, birkaç teknik kullanılarak ile karakterize edilmiştir. Hazırlanan yüzeyin kararlılığı gösterilmiştir. MDT ile modifye edilmiş GCE, su örneklerinde Cd(II) iyon analizi için kullanılmıştır. Derişim aralığı ve deteksiyon limiti sırasıyla 1.0×10-9 - 1.0×10-8 M ve 2.0×10-10 M, olarak bulunmuştur.Kadmiyum son yıllarda sadece insan yaşamını değil doğa ve yaşam alanını da tehdit etmektedir. Ayrıca, toksik olmasından dolayı kadmiyum kullanımı genellikle azalmaktadır.

Cadmium is recently threatening not only the life of man but also nature and living environment. In addition, cadmium usage is generally decreasing because it is toxic. 3-Methyl-4-(4-hydroxybenzylidenamino)-4,5-dihydro-1H-1,2,4-triazol-5-one (MDT) in 0.1 M supporting electrolyte was attached to glassy carbon electrode (GCE) by the phenol oxidation. The modified surface was investigated by several methods. The stability of the prepared surface was presented. The GCE with MDT was utilized for Cd(II) ions analysis in water samples. The concentration range and the detection limit were 1.0×10^-9-1.0×10^-8 M and 2.0×10^-10 M, respectively.
