Separation of Thiourea and Ammonium Thiocyanate

open access: yesBUNSEKI KAGAKU, 1954
Ammonium thiocyanate and thiourea are interchangeable isomers. The authors found that treating a mixture of these two with mercuric chloride gives a precipitate of thiourea above pH 4, while the ammonium thiocyanate does not give precipitate below pH 6; thus, the thiourea is precipitated with mercuric chloride at pH 46 to separate from ammonium ...

UV Radiation and the reaction between ammonium and thiocyanate under prebiotic chemistry conditions [PDF]

open access: yesJournal of the Serbian Chemical Society, 2010
The reaction between ammonium and thiocyanate under prebiotic chemistry conditions was studied using FT-IR spectroscopy. Ammonium thiocyanate (1.0×10-3 mol L-1) was dissolved in sodium chloride solution (28.57 g L-1) at two different pH values (5.30 and ...

Development of ionophore-based nanosphere emulsion incorporating ion-exchanger for complexometric titration of thiocyanate anion

open access: yesJournal of Advanced Research, 2017
Ionophore-based ion-exchange nanosphere emulsion was prepared and tested for the determination of thiocyanate. The emulsified nanosphere contained the cationic additive tridodecylmethyl ammonium chloride (TDMAC), the plasticizer, and the ionophore Mn(III)

Theoretical description of the ligand function for ionoselective electrodes reversible to metal anion complexes. 2. Selectivity to foreign ions

open access: yesЖурнал Белорусского государственного университета: Химия, 2020
Within the framework of the steady-state diffusion model, the equations have been obtained explicitly describing the selective electrode selectivity coefficient to the ligand ion in relation to foreign ions not forming complexes with zinc ions, as a ...

Gold phytoextraction and mining-degraded soil reclamation

open access: yesActa Agronómica, 2017
Gold phytoextraction is a technology used to obtain this metal (Au) throughout plants. Some of the benefits of this technology are the mitigation of the environmental impact, the fact that it does not imply the constant use of pollutants, and has the ...

(2-Acetylphenolato)(2-{1-[2-(morpholin-4-yl)ethylimino]ethyl}phenolato)(thiocyanato-κN)cobalt(III)

open access: yesActa Crystallographica Section E, 2011
The title mononuclear cobalt(III) complex, [Co(C14H19N2O2)(C8H7O2)(NCS)], was obtained by the reaction of 2-acetylphenol, 2-(morpholin-4-yl)ethylamine, ammonium thiocyanate and cobalt nitrate in methanol. The CoIII atom is coordinated by one phenolate O,
