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 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 کاملPhotocatalytic degradation of rhodamine B by nano bismuth oxide: Process modeling by response surface methodology (RSM)
The photocatalytic activity of nano-Bi2O3 was evaluated in degradation of rhodamine B (RhB) as a model of dye pollutant from waste waters. Nano sized Bi2O3 was synthesized using the chemical precipitation method. The as-prepared sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spect...
متن کاملAdsorption kinetics of Rhodamine-B on used black tea leaves
Rhodamine B (Rh-B) is one of the most common pollutants in the effluents of textile industries effluents in developing countries. This study was carried out to evaluate the applicability of used black tea leaves (UBTL) for the adsorptive removal of Rh-B from aqueous system by investigating the adsorption kinetics in batch process. The effects of concentration and temperature on adsorption kinet...
متن کاملEffect of WO3 Nanoparticles on Congo Red and Rhodamine B Photo Degradation
Tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. Photo degradation of Congo Red (azo dye) showed that photo catalytic property of the as-prepared WO3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. Photo degradation of Rhodamine B (...
