A novel electroanalytical procedure is proposed for the determination of the triflumizole in formulation, soil and natural water samples using differential pulse polarography (DPP). Triflumizole exhibited a single well-defined cathodic peak over the pH range of 1.0-9.0 in Britton-Robinson (B-R) buffers. The peak potentials were shifted to more negative values upon increasing the pH and a plot o...

The voltammetric behaviour of quetiapine (QTP) was studied using direct current (DCt), differential pulse (DPP) and alternating current (ACt) polarography. The drug manifests cathodic waves over the pH range of 6 – 11.8. The waves were characterized as being irreversible, diffusion-controlled with limited adsorption properties. At pH 8, the diffusion current-concentration relationship was recti...

The liver is known to accumulate many trace elements; thus it is very important to determine their level in a sensitive way. The objective of this study was to develop a simple method for the simultaneous determination of trace elements in cow liver in which the elimination of interference can be accomplished. It was observed that Cd, Pb, Zn, and Cu ions could not be determined correctly in the...

A differential pulse polarographic method for the determination of copper, zinc and selenium in chicken liver is described. It was possible to determine these elements in a single sample solution after acid digestion. Dried liver samples weighing about 3 g were digested using HNO3 and HClO4 acids. Britton-Robinson or acetate buffer has been found suitable as the supporting electrolyte. For the ...

A highly selective, sensitive, rapid and economical differential pulse polarographic method has been developed for the determination of trace amounts of cadmium in various samples after the adsorption of its 1-(2-pyridylazo)-2-naphthol (PAN) complex on microcrystalline naphthalene in the pH range of 8.2-11.0. After filtration, the solid mass is shaken with 9.0 mL of 1 M hydrochloric acid and ca...

It is exactly one hundred years ago when the first paper about development of polarography was published in 1922. Polarography considered a predecessor voltammetry, and this iconic electrochemical technique designed by Nobel laureate Jaroslav Heyrovsky. In short review, aim to highlight some most important achievements voltammetry so far. While hints are given theoretical works related various ...

A new and simple differential pulse polarographic procedure was established for the trace determination of mercury(II). An indirect method had to be used since no polarographic peak can be observed for its direct determination. According to their standard potentials, the reaction between SO2− 3 and Hg(II) was suitable. The peak height of sulfite at about –0.70 V (pH 6, 7) was sharp, high, and v...
