Electrochemical Determination of Dopamine and Uric Acid Using Poly(proline) Modified Carbon Paste Electrode: A Cyclic Voltammetric Study

A cyclic voltammetric technique was used for electropolymerisation of proline on the surface of carbon paste electrode and for individual and concurrent determination of dopamine (DA) and uric acid (UA). The surface morphology of the developed electrode was studied by using field emission scanning electron microscopy. The modified electrode showed a high current response towards DA as compared to the bare electrode. The developed modified electrode shows good catalytic activity with a different oxidation potential of DA and UA.

Ferrocenylmethylnucleobases Synthesis, DFT Calculations, Electrochemical and Spectroscopic Characterization

Three ferrocenylmethylnucleobases (FcMeNb) were synthesized and characterized by cyclic voltammetry, electronic absorption, FT-IR and NMR spectroscopy. The energy of frontier molecular orbitals was determined using DFT/B3LYP method combined with 6-311++G(d,p) basis set in acetonitrile. The lower standard rate constant values of the FcMeNb compounds as compared to ferrocene indicated slower electron transfer kinetics.

Sonoelectrochemical synthesis of silver nanoparticles in polyvinylpyrrolidone solutions

The results of investigations of the influence of main parameters (surfactant concentration and temperature) on the synthesis of silver nanoparticles (AgNPs) by the sonoelectrochemical method in polyvinylpyrrolidone (PVP) solutions by cyclic voltammetry (CVA) are presented. It is shown that the ultrasonic field (22 kHz) leads to an increase in the anodic and cathodic currents by ~30%.

Influence of electrode material on the electrochemical behavior of the absorbing solution of the quinhydrone method of gases purification from hydrogen sulfide

The electrochemical behavior of carbonate solutions of the quinhydrone at different concentrations 1, 5, 10, 20, and 30 g/dm3 at the exposure time 0…12 days on different electrode materials - Ni and Au were studied by the cyclic voltammetry (CV) method. The catalytic properties of gold different from nickel in the anodic oxidation reactions of the quinhydrone catalyst are noted.

Electrosynthesis of Poly(selenophene-co-thiophene) Films in Boron Trifluoride Diethyl Etherate/Ethyl

Electrosynthesis of selenophene-thiophene copolymers was successfully realized at con¬stant electrode potential in a binary solvent system consisting of boron trifluoride-ethyl ether and an additional amount of ethyl ether (mole ratio 1:2). The homo- and copolymer films obtained were studied and characterized with cyclic voltammetry and FTIR spectroscopy. The influence of the applied polymerization potential and the monomer feed ratio of selenophene and thiophene on the copolymer materials was investigated.
