Adsorptive 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 کاملCathodic adsorptive stripping voltammetric determination of prednisolone in pharmaceutical preparation and human urine.
Differential pulse cathodic adsorptive stripping voltammetric method was developed for the determination of prednisolone based on electrochemical reduction of the drug at a hanging mercury drop electrode (HMDE) in 0.04 M Britton-Robinson buffer pH 3.5. The peak current varied linearly over the concentration range 7.21-144.2 ng/ml prednisolone with limit of detection and limit of quantification ...
متن کاملDetermination of losartan and triamterene in pharmaceutical compounds and urine using cathodic adsorptive stripping voltammetry.
A square-wave voltammetric procedure for the electroanalytical determination of losartan and triamterene in Britton-Robinson buffer (pH 3.0, 0.1 mol L(-1)) as a supporting electrolyte containing 30 ng mL(-1) of copper ions was developed. Opposite to the case of triamterene, losartan can not be reduced at a mercury electrode alone, but a new peak appears at -0.25 V in the presence of copper due ...
متن کاملCathodic Stripping Voltammetric Determination of Febuxostat in Pharmaceutical Dosage Form and Plasma Samples
Febuxostat FEB was determined by differential pulse “DP” adsorptive stripping voltammetry and hanging mercury drop electrode. In 0.04 mol L Britton-Robinson buffer solution, pH 10, an irreversible electrochemical reaction took place at about -350 mV, and the peak current was linearly varied over the concentration range of 12.5-200 ng mL FEB, with correlation coefficients of 0.9995, after 60 s a...
