Electro analysis of 2-Aminothiazole (2-AT) by a low cost poly Glycine modified Pencil Graphite Electrode (poly Gly/PGE) was studied using of cyclic voltammetric (CV) and differential pulse voltammetric (DPV) techniques. The optimal experimental conditions to determine 2-AT was setup by the variation of the current with scan rate, concentration and pH. Electrochemical performance of the 2-AT at ...

Sensitive electrodes based on complexing azulene polymer films were prepared by electrochemical deposition glassy carbon electrodes. The characterization of 4-(azulen-1-yl)-2,6-bis((E)-2-(thiophen-2-yl)vinyl)pyridine (M) and its polymerization performed voltammetric methods disk working in millimolar solutions acetonitrile the presence 0.1 M tetrabutylammonium perchlorate (TBAP). containing (th...

Aged distilled beverages (cognac and brandy) contain phenolic antioxidants as their quality markers. Voltammetric sensors based on the carbon nanotubes electropolymerized pyrocatechol violet (PCV) or p-aminobenzoic acid (ABA) were developed for simultaneous determination of in cognac brandy. The polymerization conditions PCV ABA optimized. Sensors allow sensitive gallic ellagic acids well syrin...

Abstract Study of the use polymers with higher conductivity like polypyrrole, and polyaniline in electrochemical insulin sensors can overcome drawbacks arising from ongoing non-conductive polymer membrane. Conductive membranes maintain positive properties polymers, improved stability, reproducibility, even increase current response prepared sensor toward oxidation. Three different screen-printe...

We report on a novel voltammetric detection of oxalic acid by using glassy carbon electrodes with covalently attached nitrogen-containing functional groups prepared by stepwise electrolysis. A glassy carbon electrode electrooxidized in an ammonium carbamate solution was electroreduced at -1.0 V (vs. Ag/AgCl) in 1.0 M sulfuric acid for a long time. We found that the electrocatalytic oxidation wa...
