[ 1 ] - Direct Electrochemistry of Polyphenol Oxidase
The electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) is presented. Cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (PPO). A redox couple with an anodic and counterpart cathodic peak is obtained. The influence of various parameters such as pH,...
[ 2 ] - Preparation of Poly-N-Methylpyrrole Coated Platinum Modified Electrode in Chloroform in the Presence of Various Supporting Electrolytes and Its Use for the Catalytic Oxidation of Ascorbic Acid and Hydroquinone
The electrochemical preparation of poly-N-methylpyrrole (PMPy) coated platinum electrode in chloroform in the presence of tetrabutylammonium Perchlorate, hexafluorophosphate, hydrogensulphate, Periodate and Iodide as supporting electrolytes was performed. The influence of electrosynthesis method, dopant anion type and operation temperature on electrochemical behavior of polymer were demonst...
[ 3 ] - A Cyclic Voltammetric Study of the Aqueous Electrochemistry of Some Anthraquinone Derivatives on Carbon Paste Electrode
The aqueous electrochemistry of a number of anthraquinone derivatives was studied by using cyclic voltammetry at the surface of carbon paste electrode (CPE). From measurements of the half-wave potential as a function of pH, the potential - pH diagrams were constructed for each compound. The values of formal potentials and the pK'a of some different redox and acid-base couples inv...
[ 4 ] - Highly improved methanol oxidation onto carbon paste electrode modified by nickel particles dispersed into poly (2,5-dimethylaniline) film
In this work, modification of carbon paste electrode surface with poly (2, 5-Dimethyl aniline) (P-2,5-DMA) by using electrochemical polymerization was described. Then, transition metal ions of Ni(II) were incorporated into the polymer film by two ways. At first way, the polymeric modified electrode was immersed in 0.2 M NiSO4 solutions and the second way was carried out by electrodeposition of ...
[ 5 ] - The Mathematical Description for CoO(OH)-Assisted Hydroxylamine Electrochemical Determination in Neutral Media
The possibility of hydroxylamine electrochemical determination over a CoO(OH)-modified electrode, accompanied by complex-formation, has been studied from the theoretical point of view. The correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis. It was shown that CoO(OH) may be applied as an efficient electrode modifier i...
