Precipitation of uranyl ion in fused potassium thiocyanate

Potassium Thiocyanate in the Treatment of Hypertension *

Ever since Pauli' first recommended thiocyanates for the treatment of hypertension almost forty years ago, the therapeutic value of these drugs has been a subject of controversy. Interest apparently declined after Ayman's pronouncement,' in 1931, that thiocyanates lacked dinical usefulness because there appeared to be an insufficient margin of safety between the hypotensive and the toxic doses....

Solvation Phenomena of Potassium Thiocyanate in Methanol–Water Mixtures

This paper reports the results of a variety of experiments carried out for understanding the solvation behavior of potassium thiocyanate in methanol–water mixtures. Electrical conductivity, speed of sound, viscosity, and FT-Raman spectra of potassium thiocyanate solutions in 5 and 10% methanol–water (w/w) mixtures were measured as functions of concentration and temperature. The conductivity and...

Continuous monitoring using thiocyanate ion-selective electrodes

Uranyl precipitation by Pseudomonas aeruginosa via controlled polyphosphate metabolism.

The polyphosphate kinase gene from Pseudomonas aeruginosa was overexpressed in its native host, resulting in the accumulation of 100 times the polyphosphate seen with control strains. Degradation of this polyphosphate was induced by carbon starvation conditions, resulting in phosphate release into the medium. The mechanism of polyphosphate degradation is not clearly understood, but it appears t...

Thiocyanate determination by ion pair chromatography

Department of Analytical and Environmental Chemistry, Vilnius University, Naugarduko 24, LT-03225 Vilnius, Lithuania A simple and rapid ion pair chromatographic method has been developed for the determination of thiocyanate. Separation was carried out on a 25 cm × 4.6 mm Ascentis C18 column (5 μm particle size) with a mobile phase containing 2 mmol/l tetrabutylammonium (TBA)-phosphate (pH 6.5) ...
