The electrochemical properties of a modified carbon paste electrode with the synthesized compound of 2,2'-[1,7–heptanediylbis(nitrilomethylidene)]-bis(4-hydroxyphenol) (DHBH) and graphite nanoparticle (GN) were studied by cyclic voltammetry (CV), chronoamperometry and differential pulse voltammetry (DPV) methods. The proposed electrode shows excellent electrocatalytic activity towards the oxida...
متن کاملIon Selective Carbon Paste Electrode For The Determination Of Flavoxate Muscle Relaxant Drug In Pharmaceutical Formulation
Abstract The utility of carbon paste electrode for the determination of flavoxate HCl modified with flavoxate-tetraphenylborate (FLX-TPB) and flavoxate-phosphotungestic acid (FLX-PTA) ion-pairs in batch mode is demonstrated. The electrodes revealed a Nernstian response over a wide concentration ranges 1.39×10-5-1x10-2 mol L-1 and1×10-5-1x10-2 mol L-1 using FLX-TPB and FLX-PTA, respectively. The...
