Quantification of lead in cooking utensils and vegetables using square wave anodic stripping voltammetry
A simple and sensitive voltammetric method using in-situ bismuth film modified glassy carbon electrode (BiFGE) and Nafion-coated bismuth film modified glassy carbon electrode (NC-BiFGE) were used to determine the amount of lead(II) present in locally produced (at Kombolcha, 376 km North of Addis Ababa, Ethiopia) and imported cooking utensils and vegetable samples before and after cooking with t...
متن کاملSquare wave adsorptive stripping voltammetric determination of diazinon in its insecticidal formulations
The pesticide diazinon was determined in its insecticidal formulations by square wave adsorptive stripping voltammetry. The method of its determination is based on the irreversible reduction reaction at the hanging mercury drop electrode. The optimal signal was detected at -1.05 V vs. Ag/AgCl in Britton-Robinson buffer at pH 4.4. Various parameters such as pH, buffer concentration, frequency, a...
متن کاملDevelopment of square-wave adsorptive stripping voltammetric method for determination of acebutolol in pharmaceutical formulations and biological fluids
A validated simple, rapid, sensitive and specific square-wave voltammetric technique is described for the determination of acebutolol (AC) following its accumulation onto a hanging mercury drop electrode in a Britton-Robinson universal buffer of pH 7.5. The optimal procedural conditions were: accumulation potential Eacc = - 0.8 V versus Ag/AgCl/KCl, accumulation duration tacc = 30 s, pulse-ampl...
متن کاملStability Indicating Square-Wave Stripping Voltammetric Method for Determination of Gatifloxacin in Pharmaceutical Formulation and Human Blood
Um método de voltametria de re-dissolução catódica adsortiva de onda quadrada, indicativa de estabilidade, completamente validado, sensível e preciso foi desenvolvido para determinação de gatifloxacina na forma bruta, em formulações farmacêuticas e em amostras de plasma e soro humano. Os limites de detecção encontrados de gatifloxacina na forma bruta e no soro humano foram 1,5 × 10 e 2,2 × 10 m...
متن کاملSquare wave voltammetric quantification of folic acid, uric acid and ascorbic acid in biological matrix
Nowadays, modified electrodes with metal nanoparticles have appeared as an alternative for the electroanalysis of various compounds. In this study, gold nanoparticles (GNPs) were chosen as interesting metal nanoparticles for modifying of carbon paste electrode (CPE). GNPs and the gold nanoparticles-modified carbon paste electrode (GNPs/CPE) were characterized by UV-Vis spectroscopy, transmissio...
