4-amino-3-hydrazino-5-mercapto-1,2,4-triazole (Purpald® )'un Elektropolimerizasyonu

Bu çalışmada, tek kullanımlık kalem grafit elektrot (PGE) üzerinde 4-amino-3-hidrazino-5-merkapto-1,2,4-triazolün (Purpald®) elektropolimerizasyonu tanımlanmış ve polimer film kaplı ve çıplak PG'nin elektroaktivitesi, pH 8 Britton Robinson (BR) tampon çözeltisi içerisinde hazırlanan $K_3lbrack Fe{(CN)}_6rbrack;/;K_4lbrack Fe{(CN)}_6rbrack$ çözeltisi ile test edildi. Purpald® filminin elektropolimerizasyonu döngülü voltammetri (CV) ile yapıldı. Elektrokimyasal empedans spektroskopisi (EIS) kullanılarak, Purpald® film kaplı elektrotun optimum koşulları belirlenmiştir. Purplad® ile modifiye edilmiş elektrotların iletkenliği, EIS tekniği ile çıplak ve p-fenilendiamin ile modifiye edilmiş PG elektrotları ile karşılaştırıldı. Sonuçlar, elektrosentezlenmiş poli (Purplad®) filmin, elektrokimyasal analizlerde ve sensör uygulamalarında kullanılacak elektrotların modifikasyonu için kullanılabileceğini göstermektedir.

Electropolymerization of 4-amino-3-hydrazino-5-mercapto-1,2,4- triazole (Purpald®)

In this study electropolymerization of 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole (Purpald®) on the disposable pencil graphiteelectrode (PGE) was described and the electroactivity of the polymer film coated and naked PG electrodes were checked against$K_3lbrack Fe{(CN)}_6rbrack;/;K_4lbrack Fe{(CN)}_6rbrack$ in pH 8 Britton-Robinson (BR) buffer solution. The electropolymerization of Purpald® film wasperformed with cyclic voltammetry (CV). The optimal conditions of Purpald® film coated electrode were performed usingelectrochemical impedance spectroscopy (EIS). The conductivity of the Purplad® modified electrodes was compared with bare and pphenylenediamine modified PG electrodes by EIS technique. The results indicated that electrosynthesized poly(Purplad®) film couldbe used for modification of electrodes to be used in electrochemical analysis and sensor applications.
