Extraction Mechanism of Bismuth(III) with Trioctylmethylammonium Nitrate.

Uranium Extraction from Solid Waste as Nitrate Complex with D2EHPA, TOPO and their Synergistic Mixture

Solvent extraction of Gd(III) from perchlorate and nitrate media with mixtures of thenoyltrifluoroacetone and Benzo-15-Crown-5

The extraction of Gadolinium (Gd) from perchlorate and nitrate media in 1,2-dichloroethane(C2H4Cl2), carbon tetrachloride (CCl4) and chloroform (CHCl3) by mixtures of 2-thenoyltrifluoroacetone (HTTA) and a crown ether benzo-15-crown-5 (B15C5) is investigated.The composition of the extracted species is determined as Gd(TTA)3.nB15C5 (n=1 in nitratemedium and n=2 in perchlorate medium). The values...

Combating nitrate tolerance: a novel endogenous mechanism.

With glycerol trinitrate (GTN) as the prototype, nitrates represent one of the safest and most rapidly effective pharmacological means to reduce acute symptoms of myocardial ischemia attributable to obstructive coronary disease. This has led, over the years, to the development of long-acting oral and topical preparations. However, efficacy with chronic administration is more difficult to achiev...

Solvent Extraction of Neodymium(III) by Functionalized Ionic Liquid Trioctylmethylammonium Dioctyl Diglycolamate in Fluorine-free Ionic Liquid Diluent

The extraction behavior of neodymium and other rare earths from nitric acid media by the functionalized ionic liquid trioctylmethylammonium dioctyl diglycolamate, [A336][DGA], was investigated. The nonfluorinated ionic liquid trioctylmethylammonium nitrate, [A336][NO3], was used as diluent. The extraction behavior of neodymium(III) in this ionic liquid solution was carried out as a function of ...

Use of protein in extraction and stabilization of nitrate reductase.

The in vitro instability of nitrate reductase (EC 1.6.6.1) activity from leaves of several species of higher plants was investigated. Decay of activity was exponential with time, suggesting that an enzyme-catalyzed reaction was involved. The rate of decay of nitrate reductase activity increased as leaf age increased in all species studied. Activity was relatively stable in certain genotypes of ...
