Cathodic Adsorptive Stripping Voltammetric Determination of the Antitumor Drug Rutin in Pharmaceuticals, Human Urine, and Blood Serum
Cathodic adsorptive stripping voltammetry (CASV) was applied for the determination of rutin in pharmaceuticals, human urine, and blood serum. An electrochemical stripping procedure for trace measurements of rutin was developed based on the adsorption of the Cu2þ-rutin complex on a hanging mercury drop electrode and applied to the quantification of the drug. Cyclic voltammetry was used to charac...
متن کاملDetermination of ultra trace Uranium in Lichen by Adsorptive-Cathodic Stripping Voltammetric Technique
Cathodic Stripping Voltammetric (DPAdCSV) method was optimized and validated for the determination of uranium (U) in lichen using choranilic acid (CAA) as complexing agent. The complex can be used for a selective and ultra-trace determination of 'U' by adsorptive cathodic stripping voltammetry (AdCSV) using a hanging mercury drop electrode (HMDE) as working electrode. The method was validated b...
متن کاملAdsorptive Cathodic Stripping Voltammetric Determination of Ciprofloxacin in Bulk Powder, Pharmaceutical Dosage Forms and Urine
Purpose: To investigate the electro-reduction behaviour and determination of ciprofloxacin using a hanging mercury drop electrode. Methods: Cyclic voltammograms of ciprofloxacin recorded in Britton – Robinson buffers pH 2 – 5 exhibit a single irreversible cathodic peak. The dependence of the peak current and peak potential values on buffer (nature, pH and concentration) and accumulation conditi...
متن کاملAdsorptive Cathodic Stripping Voltammetric Determination of Cefoperazone in Bulk Powder, Pharmaceutical Dosage Forms, and Human Urine
The electroreduction behaviour and determination of cefoperazone using a hanging mercury drop electrode were investigated. Cyclic voltammograms of cefoperazone recorded in universal Britton-Robinson buffers pH 3-6 exhibited a single irreversible cathodic peak. The process was adsorption-controlled. Britton-Robinson buffer 0.04 M pH 4.0 was selected as a supporting electrolyte for quantitative p...
متن کاملVoltammetric characteristics of miconazole and its cathodic stripping voltammetric determination.
Miconazole is reduced at mercury electrode above pH 6 involving organometallic compound formation, responsible for an anomalous polarographic behavior. The electrodic process presents a large contribution of the adsorption effects. The drug can be determined by cathodic stripping voltammetry from 8.0 x 10(-8) to 1, 5 x 10(-6) molL-1 in Britton-Robinson buffer pH 8.0, when pre-accumulated for 30...
