چکیده
In the present work, it has been shown that bismuth film electrodes deposited on screen-printed carbon supports could be successfully used to provide well-shaped, sensitive and reproducible catalytic adsorptive stripping signals of Ge(IV) in presence catechol V(IV)-HEDTA (HEDTA-N-hydroxyethyl-ethylene diamine-triacetic acid) complex.

Adsorptive stripping voltammetric methods for determination of aripiprazole
Anodic behavior of aripiprazole (ARP) was studied using electrochemical methods. Charge transfer, diffusion and surface coverage coefficients of adsorbed molecules and the number of electrons transferred in electrode mechanisms were calculated for quasi-reversible and adsorption-controlled electrochemical oxidation of ARP at 1.15 V versus Ag/AgCl at pH 4.0 in Britton-Robinson buffer (BR) on gla...
متن کاملAdsorptive stripping voltammetric determination of ketoconazole in pharmaceutical preparations and urine using carbon paste electrodes.
The oxidation of ketoconazole on a bare carbon paste electrode was studied voltammetrically. The results indicated that the process is irreversible and controlled by an adsorption-extraction process which allows the accumulation of the drug at the electrode surface. After the optimization of solution pH, accumulation variables and instrumental parameters, sensitive differential pulse and linear...
متن کاملDetermination of ultra trace of thiosemicarbazide by adsorptive stripping voltammetric method
In the present work, an adsorptive stripping voltammetric method using a hanging mercurydrop electrode (HMDE) was described in order to determine the ultra trace of thiosemicarbazidein different real samples. The method is based on accumulation of thiosemicarbazide on mercuryelectrode. The potential was scanned to the negative direction and the differential pulse strippingvoltammograms were rec...
متن کاملMercury Thin Film at Glassy Carbon Electrode for Adsorptive Stripping Voltammetric Determination of Captopril in Pharmaceutical Samples
A simple square-wave adsorptive voltammetric (SWAV) method was developed for determining Captopril (CAP) in pharmaceutical formulations. The proposed method was based on the electrochemical reduction of CAP at a mercury thin film electrode (MTFE). The preparation of the TMFE/Glassy carbon electrode was very simple; also, this electrode had very good reproducibility and regeneration of its surfa...
متن کاملHighly sensitive adsorptive stripping voltammetric method for the ultra-trace determination of chromium(VI).
A rapid differential pulse adsorptive stripping voltammetric method has been developed for the ultra-trace determination of chromium using 2,2'-bipyridine. The base electrolyte used is 0.1 M NH4Cl (pH 6.0). The peak current was found to increase substantially with the addition of nitrite ions. A well-defined peak was observed at -1.3 V. Parameters, like concentration of the ligand, concentratio...
