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.
