Analysis of Pesticide Residues by Polarography

MediSign - Secure Pharmaceutic Distribution

Durch das MediSign Projekt soll gezeigt werden, wie man durch Einsatz von RFID-Technologie und digitaler Signaturen die Vertriebswege von Medikamenten sichern kann. MediSign kann dabei einen fälschungssicheren Transport der Ware vom Produzenten über beliebige Zwischenstufen bis hin zum Konsumenten garantieren. MediSign versteht sich als Dienstleister eines Services zur digitalen Absicherung, de...

Polarography in Molten Salts

TYPES OF MELTS From the practical viewpoint, melts may be classified according to melting points which may limit the available techniques. The lowest melting, with working temperatures up to 250°, are typified by the LiNO3—NaNO3— KNO3 eutectic, NaNO3—KNO3 eutectic, LiClO4, and ammonium formate. With these solvents it is possible to use the dropping mercury electrode, or hanging mercury drop ele...

Electrochemical Analysis of Antichemotherapeutic Drug Zanosar in Pharmaceutical and Biological Samples by Differential Pulse Polarography

The electrochemical reduction of zanosar was investigated systematically by direct current polarography, cyclic voltammetry, and differential pulse polarography (DPP). A simple DPP technique was proposed for the direct quantitative determination of anticancer drug zanosar in pharmaceutical formulation and spiked human urine samples for the first time. The reduction potential was -0.28 V versus ...

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...
