Estimation of Tegaserod Maleate by Differential Pulse Polarography
A highly sensitive differential pulse polarographic method has been developed for the estimation of tegaserod maleate after treating it with hydrogen peroxide solution. The oxidation of tegaserod maleate is a reversible process as the oxidized product could be reduced at hanging mercury drop electrode in a quantitative manner using differential pulse polarography mode. The limit of quantificati...
متن کاملTrace 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...
متن کاملSelective 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...
متن کاملReverse Differential Pulse Voltammetry and Polarography
In this paper we obtain the analytical solution for the reverse Werential pulse O P ) technique for a slow electronic transfer process, starting fkom expressions obtained previously for the faradaic response to a triple potential pulse. The solutions are valid for the planar approximations of a static mercury drop electrode and of a dropping mercury electrode. An irreversible reduction process ...
متن کاملIndirect determination of thallium by differential-pulse polarography.
The method is based on the separation of Tl(I) as Tl(2)HPMo(12)O(40), stripping of the molybdate, and measurement of the peak current in differential-pulse polarography of the molybdenum. The calibration graph is linear over the range 2-12 ppm of thallium. The relative standard deviation is 1.2% (7 replicates each containing 500 microg of thallium). The current due to reduction of the molybdenu...
