A new and simple procedure for the trace determination of mercury using differential pulse polarography and application to a salt lake sample

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...

Application of Differential Kinetic Method Using ANN with a New Synthetic Reagent for Simultaneous Spectrophotometric Determination of Mercury and Palladium

A new selective reagent was used for simultaneous determination of mercury and palladium in real samples with their different kinetic spectrophotometric properties. The method is based on the difference in the rate of the oxidation reaction of the recently synthesized reagent, nitro benzoyl diphenylmethylen phosphorane (N-BDMP), with Hg2+ and Pd2+. The kinetic profiles were monitored and record...

Trace Determination of Azathioprine by Differential Pulse Polarography

A simple and rapid differential pulse polarographic method was developed for the trace determination of azathioprine. A welldefined polarogram with three peaks was obtained in acetate buffer (pH 5.0) with peak potentials -0.27 V, -0.73 V and -1.02 V. The current-concentration linearity was found extend up to 5 x 10 mol L (r = 0.9992) with minimum detection limit of 2.8x10 mol L. The values of r...

Selective Determination of Trace-Bismuth by Extraction-Differential Pulse Polarography in Non-Aqueous Media

The voltammetric characteristics of bismuth(III)-oxinate in chloroform at the mercury electrode were investigated and a quasi-reversible behavior for Bi(III) oxinate reduction was confirmed. Preceded by the extraction of Bi(III) oxinate in chloroform, differential pulse polarography was developed in the extracts for determination of the trace-bismuth. The linear range of the calibration gra...
