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...

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...

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...

A sensitive adsorptive stripping procedure (square wave adsorptive stripping voltammetry), was developed to study the adsorption property of Eosin-Y dye on a working electrode (HMDE) and its determination in selected samples. In addition, differential pulse polarographic and cyclic voltammetric methods were used to evaluate the electrochemical preliminary studies of Eosin-Y dye. By means of usi...

Stripping voltammetry as technique has proved to be very useful in the analysis of heavy and other metal ions due to its excellent detection limits and its sensitivity in the presence of different metal species or interfering ions. Recent assessments of aquatic samples have shown increased levels of platinum group metals (PGMs) in aquatic ecosystems, caused by automobile exhaust emissions and m...

a selective and sensitive method for determination of cadmium and zinc is presented. the method is based on adsorptive accumulation of the complexes of cd (ii) and zn (ii) ions with 4-amiono-5-methyl-2,4-dihydro-3h-1,2,4-triazol-3-tion (mmtt) onto hanging mercury drop electrode (hmde), followed by reduction of the adsorbed species by voltammetric scan using differential pulse modulation. the li...

Investigation of the electrochemical behavior using cyclic voltammetry and detection of [Mn(2+)(thiophenyl-2-carboxylic acid)2 (triethanolamine)] with adsorptive stripping differential pulse voltammetry. The electrochemical behavior of a manganese(II) complex [Mn(2+)(thiophenyl-2-carboxylic acid)2(triethanolamine)] (A) was investigated using cyclic and differential pulse voltammetry in an aceta...
