Electropolymerization of Glycine at Carbon Paste Electrode and its Application for the Determination of Methyl Orange
A recently constructed polyglycine modified carbon paste electrode (PGMCPE) was employed to evaluate the electrochemical behavior of methyl orange (MO). The developed electrode was characterized by FESEM to understand the morphology of the modified electrode and bare carbon paste electrode (BCPE). The modified electrode exhibits an excellent electrochemical activity towards the oxidation of MO....
متن کاملAnodic Oxidation of α-Lipoic Acid at a Glassy Carbon Electrode and Its Determination in Dietary Supplements
Direct electrochemistry of alpha-lipoic acid (ALA) was performed at a glassy carbon electrode using cyclic, differential pulse and square wave voltammetry over a wide range of pH. The oxidation of ALA is an irreversible process, pH independent, and involves the charge transfer of one electron. The diffusion coefficient of ALA was calculated from the results obtained at pH 6.9 in 0.1 M phosphate...
متن کاملELECTROCHEMICAL OXIDATION OF ASCORBIC ACID MEDIATED BY CARBON NANOTUBES /Li/ CARBON PASTE MODIFIED SOLID ELECTRODE
Multi-walled carbon nanotube (MWCNT) was used to modify BPPG electrode because of its unique structure and extraordinary properties. MWCNT modified electrode exhibited obvious enhancing and electrocatalyzing effects to the oxidation of ascorbic acid using cyclic voltammetry technique. MWCNT was bonded on BPPG electrode surface using carbon paste with ratio of 30% (w/w) carbon paste (binder): 70...
متن کاملSimultaneous Determination of Ascorbic Acid, Uric Acid and Tryptophan by Novel Carbon Nanotube Paste Electrode
In the present paper, electrochemical methods were used to investigate the behavior of ascorbic acid at a carbon paste electrode modified with 2,2'-((1E)-(1,2 phenylenebis(azanylylidene)) bis(methanylylidene))bis(benzene-1,4-diol) (PBD) and oxidized multiwall carbon nanotubes. The modified carbon paste electrode showed high electrocatalytic activity toward ascorbic acid; the current was enhance...
