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...
متن کاملPolarography of diacetylthiamine and dibenzoylthiamine.
In recent years, a series of thiamine derivatives has been synthesized and many investigations have been made both chemically and medically. Allithiamine, a S-alkyl thiamine derivative, was studied in the previous pa per (1) and was found to have polarographically a similar behavior to thia mine. In the present experiment, polarographic investigations on diacetyl thiamine (DAT) and dibenzoylthi...
متن کاملRapid-sweep polarography of cystine.
In their brochure The Principles and Applications of Cathode-Ray Polarography Southern Analytical Ltd. (Camberley, Surrey, U.K.) refer to a paper in which one of their cathode-ray polarographs is used for the determination of amino acids containing thiol and disulphide groups (Coult, 1958). This work apparently takes no account of the fact that the shape of a rapid-sweep polarogram is more depe...
متن کاملDevelopments in Chromato-polarography
Developments in chromato-polarography and the results obtained from its application to the analysis of mixtures of organic compounds are presented. The possibility of determining traces of organic impurities in organic substances by this technique is evaluated. The polarographic method is today one of the most important instrumental methods and has found wide application in analytical chemistry...
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 ...
