Acibenzolar-S-methyl (ASM) is a novel fungicide applied for crop protection. A renewable silver amalgam film electrode was used for the determination of ASM in pH 3.4 Britton Robinson buffer using square wave adsorptive stripping voltammetry (SWAdSV). The parameters of the method were optimized. The electroanalytical procedure made possible to determine ASM in the concentration range of 5 10 –3...

We have examined the anodic stripping voltammetry (ASV) of Cd and Pb at carbon screen printed electrodes modified by an in situ deposited Bi film, and have demonstrated significant cross talk between the stripping peaks of the two metals. A simple and generally applicable method for dealing with this problem is described, based on curve-fitting three-dimensional calibration plots using MATLAB. ...

Bismuth-telluride-based alloys are currently the best commercially available thermoelectric materials for applications at room temperatures. Up to 150 micron thick layers of bismuth antimony telluride (Bi0.5Sb1.5Te3) were directly deposited onto nickel by either potenstiostatic or potentiodynamic electrodeposition. Cyclic voltammetry was employed to identify the optimal deposition potential. Th...

Solid state thin film lithium microbatteries fabricated by pulsed-laser deposition (PLD) are suggested. During deposition the following process parameters must be considered, which are laser energy and fluence, laser pulse duration, laser pulse frequency, target composition, background gasses, substrate temperature, target-substrate distance and orientation. The effects of the variations of the...

Electrodes modified layer-by-layer by self-assembly of redox active polyelectrolytes comprised of osmium bipyridine-pyridine derivatized poly(allyl-amine) and poly(vinyl) sulfonate have been studied by EQCM, ellipsometry, cyclic voltammetry and electrochemical impedance spectroscopy in aqueous solutions of different anions and cations. Redox driven swelling by solvent exchange during oxidation,...

−− The electrocatalytic properties of platinum nanoparticles incorporated into polyaniline films was investigated for oxidation of ethanol in sulfuric acid solutions. The electropolymerization of aniline and the electrochemical depositions of platinum particles into the polyaniline film were achieved by cyclic voltammetry. The effect of the formation conditions of platinum-modified polyaniline ...

Nitrogen doped diamond-like carbon (N-DLC) thin films were prepared on n-Si substrates using a filtered cathodic vacuum arc deposition method. Square wave anodic stripping voltammetry (SWASV) was used to trace Pb and Cu in a neutral KCl solution with pH 7. Stripping voltammograms of Pb and Cu were analyzed in terms of metal concentration, deposition time and deposition potential. The SWASV resu...

The application of batch injection analysis to the determination of trace metals in samples of volume s 100 ~1 by square wave anodic stripping voltammetry has been investigated in detail, using a programmable electronic micropipette. The in situ formation of a mercury film on a glassy carbon electrode substrate, the influence of preconcentration time, injection rate and injected volume of analy...

Simultaneously, the p-synephrine 1 template was imprinted, and a ferrocene redox probe covalently immobilized in (bis-bithiophene)-based polymer, resulting molecularly imprinted polymer (MIP) deposited on Pt electrode as thin film to form self-reporting MIP film-based chemosensor. After subsequent extraction from film, analyte determined with differential pulse voltammetry (DPV) (redox probe)-f...

A glassy carbon electrode, modified with gold nanoparticles/over-oxidized poly-eriochrome black T film, was fabricated for sensitive determination of As(III) by stripping voltammetry in an acidic medium. The electrode surface properties were characterized cyclic voltammetry, electrochemical impedance spectroscopy, scanning electron microscope (SEM), and X-ray photoelectron spectroscopy (XPS). d...
