Thermodynamic Studies on Phase Transitions of Potassium Thiocyanate and Ammonium Thiocyanate Crystals [PDF]
Bulletin of the Chemical Society of Japan, 1979 Abstract Heat capacities of KSCN and NH4SCN crystals were measured by adiabatic calorimetry in the temperature range between 13 K and the melting points. Molar volume of NH4SCN was also determined above room temperature. Entropy change for the II-I transition of KSCN (414.54 K, essentially higher order but accompanied with the first ...

Separation of Thiourea and Ammonium Thiocyanate
BUNSEKI 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 ...

The Role of Specific Ion Effects in Ion Transport: The Case of Nitrate and Thiocyanate [PDF]
J. Phys. Chem. C 2020, 124, 1, 573-581, 2019 The selective transport of trivalent rare earth metals from aqueous to organic environments with the help of amphiphilic "extractants" is an industrially important process. When the amphiphilic extractant is positively charged or neutral, the coextracted background anions are not only necessary for charge balance but also have a large impact on ...

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

Gold phytoextraction and mining-degraded soil reclamation
Acta 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 ...
