Bazı yeni 1,2,4-triazol türevi bileşiklerin pKa değerlerinin potansiyometrik titrasyon metodu ile susuz ortamda incelenmesi
(Rize Üniversitesi / Fen Bilimleri Enstitüsü / Kimya Anabilim Dalı, 2011)On iki 1,2,4-triazol türevi bileşiği ilk kez sentezlenerek bunların potansiyometrik incelemesi yapıldı. Bu bileşiklerin biyolojik aktif oldukları tespit edilmiştir. Bu nedenle pek çok pratik uygulamada önem kazanmışlardır. ... -
Determination of protonation constants of some 3-alkyl(aryl)-4-(p-t- butyl(benzyl/benzyliden)amino)-4,5-dihydro-1h-1,2,4-triazole-5-one derivatives in ethanol-water mixtures
(0-Belirlenecek, 2010)Stoichiometric protonation constants of some 3-alkyl(aryl)-4-(p-t- butyl(benzyl/benzyliden)amino)-4,5-dihydro-1H-1,2,4-triazole-5-one derivatives were determined potentiometrically in 50% (v/v) ethanol-water mixtures at ... -
Determination of the protonation constants of some 4-(substituted benzylamino)-4,5-dihydro-1H-1,2,4-triazol-5-ones by the potentiometric method in ethanol-water mixtures
(2007)To gain more information about the effect of solvent on 4,5-dihydro-1H-1,2,4-triazol-5-ones, the stoichiometric protonation constants of thirteen triazoles in ethanol-water mixtures were determined at an ionic strength of ... -
Development of all-solid-state antidiabetic drug metformin-selective microsensor and its electrochemical applications
(Wiley-V C H Verlag Gmbh, 2020)In this study, all-solid-state type potentiometric PVC membrane selective microsensor was developed for Metformin (MET) which is an antidiabetic drug active substance. Metformin-tetraphenylborate (MET-TPB) ion-pair was ... -
